Just watched Bigger Pockets podcast/video about picking a market here as well as read through this article about markets with both appreciation and cash flow here.First lesson - keep the end in mind.

I am in Northern Virginia as well and am about to close on my first property.

Well I have a deal under contract and I have a cash buyer.

If the sales price is $850k you will need significant down payment to carry the DSCR loan on $5300 current rents...check in with @Joseph Chiofalo  as DSCR loans 5+ units are typically a bit more difficult to place as well. 

Typically houses/properties that have well water and a septic system have them in opposing yards, and code typically demands a certain distance between them. 

Prior to this, I had 2 years of good tax returns from 1 stable job as well as my side business. 

I want to help with low-income housing in my community that I know well and I've worked in for many years. lenders sometimes want 3 deals of the same level done.

It is in a great area and cash flows well, for now. 

WE NEVER in 10 years buy in SH, pricing to high as well as taxes.

In the right area, you will probably do well.
