Real Estate Investing Part Two: The Math Behind Investing

The money and math behind investing in real estate. If you want to invest in real estate you will need to be able to do some basic math.

If you followed the advice in my first article, you now have decided where to invest and what your tenant demographic will be. The next step is to evaluate a property’s ability to make money.  When researching a second rental property, I realized I had to dive deeper to better understand the math of investment properties.

I read more detailed books, focusing on those that provided guidelines or formulas for calculating if a property can actually make money each month after all expenses.  Frank Gallinelli’s book “What Every Real Estate Investor Needs to Know about Cash Flow…and 36 Other Key Financial Measures” goes into incredible detail about how to analyze real estate deals.

The Ten Percent Rule

A quick rule of thumb, divide your annual rental income by the purchase price: if this is greater than 10% (0.1) it should be a solid investment.

Applying the 10% rule greatly reduces the number of properties to evaluate by identifying only the strongest investment properties in the area. These properties are good candidates to examine further and identify any repairs or maintenance work that will need to be done before being rental ready.

Shopping!

Now the fun starts. Time to start looking at houses!  I advise finding a real estate agent that is familiar with investment properties in the area. Sellers pay the real estate commission, so it helps the buyer to have an agent researching properties and lining up showings that fit your criteria and goals. The real estate agent should be able to screen all  properties for sale and can give you an idea of how much rent to expect.

Shopping for a rental house is a little different than shopping for your own home.  An ideal rental property looks good and will be able to withstand the wear and tear tenants will put it through.  Try not to get too attached to the houses you look at. Remember, this is a business decision.

Cash Flow

What you are really looking for is a nice home that has excellent cash flow.  Cash flow is simply your monthly income minus your monthly expenses.  It is important to predict and plan for as many monthly costs as possible in order to have the most accurate comparisons. When calculating cash flow, include things such as:

Expected rental income – compare similarly priced and sized homes in the neighborhood that are currently rented to understand monthly rental income potential.

Repairs/Maintenance – Will the home require repairs before being rented, or is it ready immediately?   How old are major items like roof, HVAC, and appliances?

Property manager fees – Will you have someone manage it for you or will you manage it yourself?  Our property manager charges 12% of each rent check; some charge a one-time fee for securing and screening a tenant, and some do a combination of fees.  Since we live far away, having a property manager is really the only option for us. A property manager should handle advertisement, screening tenants, inspections, basic maintenance, coordinating repairs, and any court actions if necessary.

Insurance –A basic fire policy will insure the structure and provide moderate personal liability protection.  I recommend you also get umbrella insurance for all your rentals to increase your overall liability protection.

Property taxes – Varies widely based on your city. You can find this on the internet or from a local real estate agent.

Advertising – You may pay for advertising or it may be included with your property manager fees.

Utilities – Some landlords pay for utilities like trash or landscaping.  I have only paid utilities between renters to keep utilities on for showing the house.

Vacancy – You have to be financially prepared to pay the mortgage if you have no tenant. I have never gone more than 2 months with an empty property but this depends on picking a desirable home in a good location that has rental demand.

Mortgage payment – I always choose a 30 year mortgage at the lowest annual percentage rate (APR) I can find.  This will be discussed in more detail in the next article.

Home owner association (HOA) fees – HOAs can provide great amenities for your renters, but they can also eat into your profits and create additional risk depending on how well or poorly the HOA is managed.  If choosing a property with an associated HOA, the association should provide some tangible benefits to the renter that can justify charging a higher rent.

To give you some real cash flow examples, my current fixed costs are listed below broken down into monthly amounts.  Maintenance can vary based on your home condition and also on the tenant.  Some tenants call to have you change a light bulb and some only call when a pipe bursts!

For this example we will use $40 a month as an estimate.  If you know a major repair will be needed on the property you will have to use a larger monthly estimate.  You might manage the property yourself saving in that category.  Remember the more expenses you predict the better your comparisons will be.

Property #1 Property #2 Property #3
Monthly Rent $1010 $775 $1050
Repairs/Maintenance $40 $40 $40
Property Management $121.20 $93 $126
Insurance $51.49 $35.91 $59.25
Property Tax $67.44 $113.73 $190.08
Advertising Included in Mgt fee Included in Mgt fee Included in Mgt fee
Utilities $0 $0 $0
Vacancy $0 $0 $0
Mortgage Payment $518 $0 $400.67
HOA fees $0 $0 $0
Cash Flow $211.87 $492.36 $234.00

When looking for a new property, my minimum cash flow requirement is $200 a month.  It may not sound like much money but it covers all expenses and allows me to build up a reserve in case of large repairs. I keep my reserves in a separate Betterment account with a 60/40 stock to bond allocation so the money can continue to grow moderately.

You can also check out our guide on how to calculate rental yields here.

Tax Deductions

These funds are used to pay for property taxes, repairs and maintenance on the properties, or a down payment for the next house.  While we are earning money each month, our tenant is paying down our mortgage for us, increasing our equity in the home and increasing our net worth.   Also unlike a primary residence where only mortgage interest and property tax is deductible, everything listed above is tax deductible.

Repairs, property management fees, mortgage interest, insurance, etc., are deductible expenses. The value of the rental property also depreciates over 27.5 years for further tax benefits.  Unless you plan on living in part of the house and renting out the other part, never purchase a home that has negative cash flow!

After calculating the expected monthly expenses for your cash flow requirement, it is time to estimate the one-time expenses to acquire the property.  What percent down will your lender require?  What are your estimated closing costs?  What renovations or repairs are needed before you can rent the property?

Renovations And Repairs

Since being an investment property owner is a business venture, I recommend renovating wisely and only when necessary to improve the monthly rental income of the property.

Last year I needed to do my first major repair on a rental house.  A water pipe under the floor of the master bathroom broke, requiring repair to the sub floor and the water pipe.  I knew the renter was leaving in a few months so I took this opportunity to completely gut the bathroom and update it.

We ended up repairing the broken pipe, laying a new tile floor, painting the walls and installing an all new shower, toilet, sink and vanity.   It is always good to know that renovations can add value to your home when you eventually sell it, but as an investor you need to know if that money is a good investment as well.

According to Scott McGillivray, the host of HGTV Income Property and author of “How to Add Value to Your Home”, the top five renovations for return on investment are:

1) Building an income suite, or “mother-in-law suite”, in your existing home —  creating a separate area or room in your home that you can rent increases the value of your property and generates monthly cash flow for you.

2) Painting – this will give your home a fresh and clean look at a low cost.

3) Renovating kitchens and bathrooms – these are the rooms tenants remember the most. They need to have a good layout and up to date appliances and fixtures.

4) Flooring – hardwood flooring that is consistent throughout the home will give a spacious and modern feel.

5) Light fixtures and door hardware – installing up to date finishings around the house can transform spaces with minimal costs.

When deciding on what renovations to conduct, look at the return on investment in terms of time it will take to pay itself back.   Adding at least 15% for unexpected expenses to the contractor’s estimate for the renovation and dividing that by the monthly rent amount will yield the number of months needed to pay off the renovation.

For my example, the final bathroom renovation cost was $5,200 for all the labor and materials and the renter was paying $910 a month.  $5200/$910 = 5.7 months for payoff.  The renovation quickly paid for itself and when the tenant moved out I was able to raise the rent by $100 and secure a new tenant.

I consider any renovation that will pay for itself in less than two years to be a smart investment.  For larger renovations like a kitchen, between 2-6 years payback could still add real value but you must look harder at the long term plan for the property and make sure the monthly cash flow still meets your requirements.

Opportunity Costs

For the final calculation we are going to determine if investing in this particular home is worth the time and money.  In order to do so you must compare using your money for this investment property against a different investment, also known as opportunity cost.

In other words, would the money spent on down payments and renovations have profited  more by simply investing in a Vanguard Real Estate Investment Trust (REIT)? To do that we are going to calculate your cash on cash return (COCR). COCR allows you to compare investing in something against the opportunity cost of investing in something else.

The first half of the COCR formula is your annual rental income cash flow.  For the second half, add up your total cash invested or how much money is needed to acquire and rent the property.  Total cash invested includes the down payment, all closing costs, renovations required to make it rentable and any carrying costs until the property is rented.

Once you have those two numbers, cash flow and total cash invested, you can easily calculate your predicted cash on cash return.

Here is an example from my most recent rental home purchase in 2014 with a 25% down payment:

COCR = (Annual Cash Flow/Total Cash Invested) x 100

COCR = ($3,083.25/$32,020.43) x 100

COCR = 9.62%

What does a COCR number mean? If your number is below 6%, your money might be better off invested somewhere else. Either a different house or a different type of investment.  A return between 6-10%  is a solid property.  It should cover your opportunity cost and help you ride through any market swings with steady and predictable monthly income.

If you are getting above 10%, you’re doing great and should try to find similarly producing properties.  Before the housing market collapse of 2009, you could put 5% or even 0% down on homes and get supersized cash on cash returns. But for now most public lenders require 20-30% down for investment properties so a 10% return is considered a good investment.

Let us compare investing the same money required to purchase and rent the example home, $32,020.43, to the Vanguard REIT (VNQ) which has a dividend yield of 3.30% ($32,020.43*0.033 = $1,056.67).

My annual cash flow of $3,083.25 is almost three times as much as the annual VNQ dividend payment of $1,056.67.   But what about the opportunity cost from the stock going up?

Well yes, VNQ was amazing the last three years, returning 16.20%. But it also has years like 2008 when it lost 37.07%.  Just like the stock markets rise and fall, home values can fluctuate as well.

The markets for both are unpredictable which is why I prefer to compare the predictable monthly income of rent checks and dividend payments to determine where to invest my money.

With any investment there is risk.  The goal is to reduce your risk by educating yourself, making the right choices and diversification.  In the next article we will continue to dive deeper into financing, look at some common mistakes people make, and discuss the power of leverage.

    Looking forward to reading this. I enjoyed your first one and look forward to the rest!

    Well put together. I own one rental aside from my primary residence but am apprehensive on purchasing another. It just seems like when you factor in my house and the rental to our net worth, it’s pretty heavily in real estate. I do think that another property is the best cash flow generator available to me, but worry I might be weighing too heavily into real estate by getting another. Heck, maybe I’m too heavy in it already. The average homeowner is probably at least 50% in “real estate” effectively.

    I’d be interested in hearing your take on borrowing money from a 401k to acquire the down payment. I’ve thought about this and think it would be smart so long as the cash flow can cover the repayment back to the 401k plan AND the mortgage.

    Thanks!

    • Allison

      There is certainly a case to be made for borrowing from your 401K for the down payment source, and reasons not to. My husband and I did borrow from his retirement account for our current primary residence. He is military and the TSP (military 401k) loan is a pretty sweet deal – $50 fee for doing the loan and currently the interest rate is 1.625%. All interest payments are to yourself, not a bank so the only factors to consider are 1) the opportunity cost of the money you are removing, 2) how stable is your job? If you lost your job you would owe all outstanding loan balances or you will get hit with withdraw fees and taxes 3) Can your property cash flow cover both your mortgage and your 401K loan? For the TSP the loan, repayment is 1-5 years so if you take out a large loan expect a high monthly payment. 4) If you alter your future 401k pre-tax contributions and instead put that money towards the loan repayment you are missing out on that year’s tax contributions and missing out on lowering your taxable income for the year.

      Personally we felt comfortable taking money from our TSP because my husband’s job is very secure and we made paying off the loan as our top debt for repayment even though it was our lowest interest loan. We might borrow against his TSP again for our next rental property purchase.

      The whole point of saving and amassing wealth is to create income when you retire. I want to create those streams of income now so I can retire sooner, so with that plan I feel it makes sense to borrow from your pile of money if it helps you create income streams now which will continue on into the future.

      Hope that helps!
