New To Bigger Pockets and Need Cash Flow Advice

[Frank LaViola]

Hi All, 

New to Bigger Pockets but started reading a couple of books. So I've owned 4 rental properties since the great recession. Purchased all on foreclosure and have done really well from a cash flow and appreciation perspective. My goal is not necessarily appreciation but its been great to have. Anyway my questions is I've been buying houses from wholesalers, we are on our third in about 4 months. The first one we kept as the ARV dropped fast, it was a condo do I learned from that. The second one is on the market now and has been for 22 days. My 2 questions are is the 70/30 rule realistic in Houston Texas adn waht is a good cadh flow benchmark for rentals in case I keep some more.

Thanks all
