I know someone who just went back to LTR in Lowell after struggling trying to get the MTR going.

I can find deals with 100k profit after a 100k rehab. 

After analyzing the local Mercer County market I've noticed there are not that many MFH that are desirable meaning cash flow can occur, but appreciation, schools and good tenants will be at risk.

 So if an agent is not strong in using social media, are there services they can outsource this task to?

-you are right to run numbers on 3 and 4 rooms, since you want this property to work as a rental property after you house hack.

I have 4 properties in WA state, an hour ferry ride from Seattle. 2 are SFH and 2 are townhomes. All are rented to great tenants. But I an looking to divest from real estate. I'm fine to do 5 year seller financing ...

If so, your valuations are high and your days on market will be long, and your list to sales price ratio won't be good. 

I don't think I need a service to do the billing as I'd just use my current management company, but I'm open to exploring this option if it makes more sense.  

Could be a form of equity you could bring to the table in partnering - in addition to cash you could throw in your purchase / sales commission as a form of equity in the deal.
