I'll definitely reach out and see if they can help.

Having said that (I'm a lawyer), here's what I'll tell you (for informational purposes only not intended to be legal advice).  

But I’ll include a link so you can check for yourself. https://www.toptenreviews.com/home/hvac/best-central-air-conditioning-units/amana-review/

I'll do my homework and report back on it.

I can see the value in that and I think I'll spend some time now figuring out what value I can bring to the table and what skills I think would compliment mine the most and then look into the idea of finding a partner to work with.

It's very likely I'll have to invest 1 to 2 hours outside my area (DMV) because houses are too expensive here. 

You force the tenants to upgrade or leave while you concentrate on the common areas.

I'll search around for property managers in the area to figure out what kinds of returns can be expected.  

thank you guys for your reply...yes I'll wait until deed gets transferred to my name...also, when i turn water on, I'll make sure that i have a plumber and 1 or two other ppk with me.i hope that since this is middle unit ob brick row houses without basement, it should be all right...but better to have things ready...also to have electric on before water.

Douglas, I’ll let you know if I find anyone worth mentioning.
