Hoping to find someone that does more than land contracts, and has a deep understanding of seller financing options. 

I have seen residential investors after 20 years or 30 years doing it and the deep lines on their face,stress, and many have had a heart attack or stroke.

The property is a ~12 foot wide and ~33 foot deep 1914 brick rowhome in Baltimore City.

Hello from the Deep South!

I know this question goes a million layers deep, but do you just go by the pictures that are posted online, or use a general calculation per square foot?

Of course there's another school of thought that would say to skip the kid stuff and jump right into the deep end...depends on temperament, how much time you have, etc.

As you probably know I need to get properties under contract at deep discounted prices in order to sell them fast.

Corner lot is 110' wide x 140' deep. house sits right in the middle and is 67' wide x 25' deep. the rest is backyard and front yard.

So if something in their lives forced their hand (death, divorce, bankruptcy, etc) to unload the units at a deep discount it could in turn tank the value of the one unit that I was going to own. 

And the network that a good developer should have are those with deep pockets and the city that helps your projects get approved.
