Lots of older houses but there seem to be several that have the potential for cash flow and while not exactly modern on the outside, have been renovated inside. 

Selling one and buying several is fine. 

I know several good ones in the area if you need. 

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?

Recommend you do several tranches versus one big policy. 

A more realistic expectation is 24 hours which will ensure we can arrange any repairs or corrections with a team, handle it in person, etc. be curious how this plays out as I worked for local developer for a while and developed several properties in Alexandria (Specifically old town) and while the city is challenging like any city - they were mostly realistic.

We've struggled with Quickbooks for the last several years (and before that I literally had a shoe box with receipts in it).

Over the last several years I've been in a heavy cycle of acquiring and building rental portfolio, flipping, contracting, and being a realtor.

The next several years are expected to be in a normal range of appreciation between 3.5 to 5%.
