Something to consider, or think about, is what we're actually doing when analyzing properties. The calculator seems to mark it down to some scientific formula, but what we're really trying to do is put all the numbers involved in owning real estate down into a usable format.
For example, what goes into owning or buying a property? You have the purchase price. If you can't buy outright in cash or use seller financing, then you probably want to get a loan from the bank. The bank will require a percentage of the purchase price as a down payment and then will give you the remaining amount of money. They also charge you an interest rate for the risk they are taking to give you that loan. From the loan they are giving you plus the interest rate, this is called the mortgage. Also, real estate purchasing comes with title fees, appraisal fees, origination fees, or otherwise known as closing costs.
What happens after you have the property? You owe the bank their money every month (the mortgage), you have to have insurance on the property, you'll be dealing with the local government in the form of property taxes whether it's real estate taxes and/or school taxes. You are on the hook for any and all maintenance repairs if the property needs painted, new flooring, fixing holes in the wall, etc. If a tenant moves out, you still have to pay the mortgage every month (vacancy) regardless of whether someone is living there or not. Every once in awhile you may have to replace the roof or heater. Consider also having landscaping done such as cutting the grass or shoveling snow. And, consider whether you want to manage it yourself or have a property management company do it.
And what makes all of this work in our favor? The money paid to you, the owner, for someone to live there (the rent). The goal is that you get enough excess in rent to pay all of the expenses and leave you some leftover (the cash flow). You also want to make sure that the amount of money you put into the deal upfront is worth the return you’re getting in the end (return on investment). If you have to put in a ton of money and you’re only getting a 1% return, well, you could just take that money and put it into the stock market. Remember, we are investing money so your return on that investment is very important.
The purpose of the BP calculator is to put it all in one place and make it easy to throw the numbers in, do all the math, and spit out figures in an easy to read format. The art in all of it is knowing what those numbers will be. Sometimes you know, sometimes you don't. That is why it's good to be conservative and always err on the high side. If a deal works with conservative numbers, it'll work even better if the numbers come in better than expected.
The 1% rule, 50% rule, etc. are just quick calculations to help you screen properties quickly. You aren't going to want to spend a lot of time doing calculations on every property that obviously won't work. Sometimes, that's just the way it is. I was finding that there weren't many small multi-family properties on the market in my immediate area. I had to go out over an hour away from where I live to find any. The numbers on two that I found seem to work. My head is telling me, "what am I missing?" For me, having a hard time finding a deal, it almost seems too good to be true or as if someone else knows something that I don't. I also have to find a bank with favorable terms so I can get preapproved. I'm dragging my feet a little bit with that. I'm also tossing the idea around whether I should ask a friend or family to go in on a deal with me so I don't have to put out a lot of my own capital to start. I have an emergency fund in place, but the chunk of savings doing nothing in the bank feels like a wide safety net that keeps me afloat. I am trying to come to terms with the fact that I may have to use all of it for this first purchase because ultimately, my goal is to build up enough cash flow to leave my job. I won't get there if I just let it sit there gaining .1% in the bank.
Let me know if you have any other questions.
