Purchased from private seller as a package deal with another home on the same street.

This is the company that will make offers on properties and handle all up front due diligence, manage the property after closing and receive and cashflows from the profits of the property.When you get a property under contract, complete the due diligence  and decide to move forward to closing  you then set up the LLC for the property in the State the property is located in as lenders are going to want the property entity located in the same state as the property.Once you complete the DD period and set up property LLC you then submit your package to lenders if you do not have a preferred lender to get Term sheets.

The fee is 8% but the management company keeps everything else:  late charges, fees for returned checks, an additional amount of rent they charge people with lower credit (0.085 x rent), plus $40 out of the rent for a Resident benefit Package that gives the tenant Liability Insurance and they get a new HVAC filter every other month..

I've been using them for 3 years on multiple properties (purchased 3 year package).

If you have any interest in jumping into the Fort Wayne market, I listed a package on Marketplace.

Every time I called the person that I am talking to all he said is he send another email inquiring about the loan package, then we wait again.

Can I use a commercial purchase agreement to buy a package of single family houses, or will I need to fill out a purchase agreement for each house? 

Make it part of a package.

I'm currently looking at a package deal on a SFH and a duplex as one purchase. 

Right hand side there is lease agreement package.
