We are currently using "hard money" to purchase properties, then rehab, and finally roll those loans into a regular bank at 80% LTV.

I went conventional and put 5% down, and had my PMI rolled in.

It doesnt say details, from the tax roll I think it has 4×one bd and 4×2bd.

Welcome @Tommy Coan to the BP community.You might want to look through the Texas real estate investor roll call here on Bigger Pockets  (http://www.biggerpockets.com/forums/585/topics/216105-texas-real-estate-investor-roll-call) for members that are close to you.

Assumptions - One seller owns all 3-4 unit apartments, cost and rents are for all four units/buildings you described.Rent Roll - Banks will certainly request the current rent rollLease - The banks want to see existing lease on the apartments.

The conventional lender is going to request from the seller the current rent roll to find out the occupancy rate ie the percentage of units being rented and how long the renter will be renting the property. 

Respect their time, but set a goal to find out exactly what they can do for you and what they need from you (e.g .PFS, rent rolls, DCR etc.)

I'd hate to be the one to "rain on the parade" so to speak, but with $500, you might as well have $0, so I'd say forget about leveraging your money and think about how you can leverage your time to increase your bank roll - that is your real asset.

They were slow rolling the dickens out of us and I wound up having to put 30% down with a conventional.
