Many Realtors will suggest purchasing a MFR using a FHA Loan, to reduce your out of pocket money.

You mean using a HML to purchase someone's home directly? 

I would recommend using a Realtor or better yet getting your license for your own access.Logan Square is virtually impossible, look at Avondale or surrounding areas.Im very familiar with Bridgeport,  looking right now there are 12 multi units under $400K.  

When using a realtor to find a property that you end up wholesaling, what is the general protocol for paying them if you assign the contract and technically never close?

The dust is not good to breathe in.Drywall can be cut with the snap and score method using a utility knife and straight edge.

@Dean Weltman Their are some banks that yes will give you a 2:1 leverage against the cash you are using as collateral but those banks are hard to find.

What would you say the typical entrance cost for a an A-class neighborhood is using a TK.

I'll be using a 5 or 10 year fixed with 20% down.

Offer #1 the buyer is using a VA loan and Offer #2 is conventional.  

There might also be the option to purchase or refiance using a commercial mortgage and 20% down or 80% LTV.
