I came here to learn a little be more. 

Each bedroom shouldn't need to go through the common area to exit the building4.

You are procrastinating on the smallest of things which means you may lack the confidence to do what you are planning to do.

Quote from @Sam Epperson: let's say I come to an agreement with the seller for them to finance some of the deal. let's also pretend the seller owns it with no debt, and we agree to 5% down, 5% rate, and 10 year balloon. how are we drafting this legal document?

A new build should require much lower maintenance expense vs a 100 year old home.Hope this helps.

if it has 1-2 years left, it would be good to know what a new roof costs. 

Scale with a long-term plan, acquiring one or two properties every few years.

That said it is possible that you need to evaluate your stays and decide if it is worth taking shorter stays or sticking to some longer stays to reduce your time commitment and maximize the revenue for time invested.

Also, I would suggest going to DIG (Diversified Investors Group) as well as DPI (Delco Property Investors) as they are two local REIA groups where you can meet other wholesalers and investors.

It's important to always put the real estate first.
