What is the formula for figuring out if rental property is worth it? I realize this will vary for different areas, mine is TN if that helps. I've seen many different answers on here that never really explained it all the way out for a newbie. Let's just say I buy a $100,000 sfh and my mortgage payment (piti) is $1,000 a month. Considering everything, what do I need to get in rent per month to make this a positive cash flow property and also what would I need to get to make this a VERY GOOD positive cash flow property? And, how did you arrive at those figures?
You would need to rent at $2300/month. This would give you $150/month in cash flow, which is the minimum I would take with that much risk (debt service). How to arrive at this is very simple:
Expenses: E = .5GR
(GR is gross rent.) Half of your expenses will go right out the door in insurance, property tax, maintenance, eviction costs, legal fees, entity structuring, advertising, accountant fees, etc. etc. etc. The only expense not covered here is your mortgage payment (debt service). Please note that this is a long term average. You should not expect that this will hold true for one property in a given month. This is why using riskier calculation factors (like .4 or .45) is a bad idea.
Net operating income: NOI = GR - E
Net operating income is what you have left after expenses have been deducted.
Debt Service (mortgage): DS = $1000
Debt service is the name investors use for the mortgage payment.
Cash flow: C = NOI - DS
Cash flow is what is left after the debt service has been deducted from the net operating income. At this point you have deducted all expenses.
Desired C = $150
I would not bother with this investment unless I cash flow at least $150/month. Most investors would be looking for something around $200/month in cash flow for a mortgage this big. This is simply an assessment of how much return you want for a given risk. $100,000 in debt is a lot of risk, and you should be looking to earn around 2% monthly return on that risk. Note that this is not 2% return on your investment because you are not investing $100,000 (you are only investing your down payment, which is hopefully very small).
Thus:
GR = DS + E + C
Gross rent must equal the sum of debt service, expenses, and desired cash flow.
GR = DS + .5GR + C
This substitution is possible because E = .5 gross rents, as already defined above.
.5GR = DS + C
.5GR = 1000 + 150
GR = 2 * 1150 = 2300
Now, all that said, this is largely a useless exercise. You cannot set the rent. The market sets the rent. If you are doing this calculation, then you are probably looking at a bad deal.
What you should be doing is determining the market rent for your potential property. Then plug it into the equation to determine your cashflow:
C = GR - E - DS
or, reformulated:
C = GR - .5GR - DS
C = .5GR - DS

be my first deal. Just in the past few days I started thinking that maybe I should be looking for rental property and if I happened to find one to fix and flip then ok. I thought it might be a little easier to find a property to rent and this would get me in the "game" and give me some experience. Is this a naive view? Any and all thoughts, ideas, wisdom or criticism is appreciated?
These are two different ball games. Rehabbing a property to flip and then renting that property out will break you. Tenants will destroy your property. If you are going to rent a property out, you want to repair it only to make it livable (not beautiful) and to avoid long-term maintenance nightmares (eg water damage).
