I have found that each time I've been about to purchase a property it "tells me" if it's a flip or a rental.

There is a recent post from this year that doesn't say good things about them, as far as the organization of the company goes.

I have some SFR rentals leased through Section 8.

Don,Further I will say that investors only equate cash flow to rental income and they are unaware of cash flow through notes and other debt obligations. now granted owning the asset also gives you tax bene's that notes do not.

Can you do two rental properties with the 400,000 in your market?

I like using the same mortgage broker lender who is investor friendly, a lot of the little banks don't know how to handle rental income and you get issues with underwriting mid deal.

This may have changed over the years, and I had already had about 6-7 yrs of a small single family rental portfolio under my belt, and W2 experience in commercial real estate.  

Rental history? 

As Bruce mentioned, simply open a bank account specifically for the rental property and run everything through there. 

I've been studying videos and personally gone through these nightmare pop-up expenses via my rental properties so it's been actually helpful in my journey trying to find my own home to live in.
