She claimed she's a lawyer with 7 figures in the bank.

I have approval from the bank for separate financing on each house.

I want to be prepared and knowledgeable when I approach the bank.  

SUBJECT TO existing mortgage of $125,000CASH TO SELLER $10,000WILL REFI BEFORE TWO YEARS ONCE PROPERTY IS STABILIZED (I deal with local community banks and will do a commercial in my LLC to cash out at 70% LTV to recoup back some of my initial investment?)

I'm paying between $6-$8 per square foot on bank foreclosure houses.

Or is it ok to hold off until the bank accepts?

I realize that the site says "In the future, we will expand in adjacent markets like multifamily acquisition and renovation, and non-bank new construction, which will greatly expand the market size addressed by Groundfloor."

I normally would not use them but my HELOC is at a bank that does not have a branch in my state and I would have to go to a branch in person to initiate the wire due to the amount. 

If we go the route of Fix and Flip, we would likely use an investor (did a rehab loan with local bank for first one), as our credit scores will likely remain low for some time.

This is one of the reasons why I believe teaming up with a mortgage banker over a bank or credit union is more beneficial to investors and consumers.
