There's other methods you can look into like cash out refinance or DSCR loans. 

After several years of this method, a spot check of total balance due from my schedules differed quite a bit from the mortgage lenders’ balance due.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

For example, I used AirDNA for a property and came up with $54,200 annual income, Pricelabs says $24,600, and my estimate based on the property my in laws stay at is $32,000.The income is the hardest for me to estimate, even using enemy method. 

Have you been able to acquire multiple properties using this method?

@Doug Davis when most of us do this rent-by-the-room method (otherwise known as "House Hacking") we are very discerning about who we rent to.

There's creative financing method to get started with 10k like seller financing or sub-to, but this will take a lot more effort.

Anyone upset by Bigger Pockets trying to sell them stuff needs to stop asking their Barber if they need a haircut.Loud Gufaw - Brilliant! 

Low down is my preferred method for sure, as I am still early into my career income wise, but more down allows the flexibility of the property to at least break even or cash flow a bit after I move out.

Hopefully someone can use my method on how I doubled my portfolio in a short period of time.
