If you do want to get involved in some calculations you could try to figure out the time value of money against its current net worth with the income the home is generating.Or ignoring the complex math problems, a good rule of thumb is if you can make 10X the yearly cash flow when selling, consider offloading the property and investing in another.Cheers! 

Simple math.

I always show potential deals beforehand and they give their honest opinion on the area, what rents will go far and they've even shied me away from a few deals I was considering because the math looked good but the area was iffy. 

Is my math correct, and am I thinking correctly in savings, did I forget something?

@Drew RamascoI don’t fancy myself a math whiz but the payments on a 30yr loan are much lower than that of a 15.

With the mortgage insurance added to the debt service, I do wonder how the math works. 

Good for taking the first step the next steps are saving as much as you can and learning the math so that you can evaluate various properties once you are comfortable with that you can get pre-approved and start seriously looking to buy.

I did the math.

I have done some rough math and as I pay him back I will still be profiting.
