DSCR loans are going to need a minimum loan amount of $100k and a down payment of 20-30%. 

That leads you to need a HML or private money (private money is my preference) so you can pay cash. 

I am going to need to get some kind of loan.

A vacant 40 unit is highly likely to need a LOT of work to start renting.Otherwise, the seller would be renting out the building to generate income and raise the sales price.You will need deep pockets for the purchase and to have any hope of financing, you will need bids & estimates to determine the total cost to get full Certificate of Occupancy.

Additionally, the sewer cleanout was damaged and needed to be replaced regardless we just didn't know until they caused the reason to need it. 7) Replaced every toilet due to damages/wear and tear and had multiple roof leaks from upper unit to lower unit.

Maybe you don't like the tone of my post, but hopefully it causes one person to think twice before blindly trusting anyone. 

The baltimore properties tend to be very old, so expect major systems to need replacement if you don't know interior condition.Who gave you the 45k estimate out of curiosity?

Just put your to-be-new company name as buyer and start the formation once the offer is accepted.If you can get the financing, you're going to need to sign personally for the loan even though the loan is in your company's name.

Mainly because Sanford has started in the past years the development of new construction homes in areas but there are still many areas with older homes that tend to need a lot of work and of course bad neighborhoods, such as anywhere else.

I'm obviously new to this and very early in the process, so I could very well be missing something obvious here and/or not have the creative muscles yet to think through another form of house hacking.
