I've run into a few of these and actually found that there was a 3-4" void above the old header that made it really easy to pop in a new door.Or like Chris mentioned above, just get unfinished hollow slabs, trim, and cut inserts to fill the void.I've run into some situations like this and generally will do what will result in easier future maintenance.  

To answer your question, things to consider when looking at a market are pop growth, job growth, home price growth, income growth, and crime reduction. 

The deal fell through but if it should pop back up I'll keep you in mind!

We will certainly see some of the 2.7 million forbearance cases pop up on MLS!

This is my first flip so I haven't found an the "mom and pop" stores yet. 

To me, this sounds like speculation and mirrors what was happening right before the "pop" in 2008-2009. 

I agree, that help should be the responsibility of the government, not individual private citizens (ie, mom and pop landlords).

Added 1.5 bathrooms, some landscaping and added an outdoor deck for outdoor living, pressure washed the home and painted the front door to provide a pop of color.

If you're looking for a primary residence that you can add some sweat equity to, you can see if any good deals pop up on your radar and then make the decision of whether to buy or keep renting.

But in reality it's probably closer to 0%, since most mom-and-pop's don't increase the rent, until the current tenant moves out.
