What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Sorry to be the bearer of bad news. 

I've  seen Finance Cowboy's (Jaren Sustar's) videos in my Instagram news feed and watched a couple of his YouTube videos.

I haven't been following this too closely but this is what many various news sources have reported and I believe that's why he's being sued and is supposedly under investigation). 

I’ve looked through ordinance documents for the city and county and haven’t found anything that makes me believe they don’t allow it.  

Especially if you have documents to prove your story.3.

If it's not a lot you could easily end up upside down in this home in a shaky market and that's bad news if the buyer/tenant becomes a problem. 

If you are buying a turn key and do not expect to take cash out for a few years just gauge that on your prepayment penalty years.Rates vary depending on credit scores, LTV, DSCR ratio, Loan amount, Property type, number of units.Good news is rates have been dropping so DSCR may not be a bad option if you buy and simply refinance in 12-24 months.

**Trust Documentation**: Some investors use a land trust to hold the property in a Subject To deal, which can protect privacy and minimize the lender’s focus on ownership transfer.6.

Hello Felicia, The good news is that rates have started to come down a bit so that can help your cashflow a little more.
