My only concern with norther lib/Fishtown is the demo of tenants as relates to the unemployment rate.. are they mainly young professionals that work in tech/finance/healthcare where jobs are secure?

Ask if there are any other terms that the seller wants, like you being responsible for a trash-out of a hoarder's former unit, demoing and removing a dilapidated garage or taking responsibility for overgrown landscaping. 

BRRR one SFR, demo the other one and build houses on the 2 new lots.

. - Project has been delayed due to Covid19 and Architect and GC issues, but we now have permits, and have started demo.

I would call a few CRM's that pop up on Google and request that they demo their mobile apps to you.

Lining up trades ahead of time, and having  material on site pre-demo.

@Chris Yang love the step by step process.  

Ended up buying for $105,000; plus the demo cost which wasn't much since I did it myself. 

Mmmmmmmmm.....demo.

the structure is solid no issues. however it will be a full gut demo and rebuild other than framing. the property is listed for 20k and i estimate (waiting on meeting with contractor on monday) around 40-50k for repairs to get it to quality standards.
