When I called back with final negotiated numbers and had it under contract, they said my score came back 725 (middle of the 3 scores) and they now want to add $2000 in closing fees to get me at 5.75 OR they may be able to do the loan with 30% down but they would have to look into it.

I read some mixed reviews saying that they have hidden charges.

I found them both when doing google searches for multifamily.loan.Realatom.com seems like a startup right out the gate that wants users to pay a one time fee for people to get access to your loan requests. 

Sure, there is a monthly fee, but a reasonable cost of doing business in my opinion.

A 30 year rate with 25% down and a 1% orig fee is 5.625%.

The catch is, there are a lot of rates and fees applied to mortgage services.

I would like to assign my contract to the investor for a fee.

I found some tenants in the apartment below me out of accident and I got a 5% "finder fee" which was awesome just for the possibility of it but it was almost no money.How much can I get to find tenants in that apartment?

The last one i beat down the door at 8am, made all of them clean the place up and then made them pay another cleaning fee. since those changes its been pretty smooth. 

So your purchase price plus closing costs are what you subtract from your selling costs to find gross profit. 3, dont forget selling costs... realtor fees and closing costs will be roughly 10% of the selling price at this price point.
