@Danielle SheridanThe ideal BRRRR method is like below:buy with cash (40k)rehab (30k)rent (cashflowing, ideally meet 1% test)cash out refi 75% of ARV (get 75k if appraised at 100k)get most, or all your money back, continue on the next oneIn reality not all deal will as sweet as this, but that's the concept.

I did another test.

You can use the cap rate and GRM as a litmus test and compare it to other buildings in the area.

If none of them have pools then it would be up to you to test the rents at that point.

I’ll have to test that. 

Research your state's requirements, some mandate a test.  

But actual rental income is not a bright line test. 

You can also run some test ads to see what kind of response you get. 

You read up on the laws, you practice with mom and dad, then you take a test and get your license, in a relatively short time.

In my area they seem to be fairly accurate, but I have only tested it on the DC Metro Area.Appreciate any input!
