I'd like to build on it (if anyone familiar with the area has a contractor they'd recommend I'm collecting names!)

Only way would be to collect a few quotes and move forward with the one that provided the best set of terms.

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560, little to no good tradelines, lots of collections & chargeoffs, recent evictions.

I need to get the collective computing power of BP together and make a ruling here: A tenant has moved in and is under a year contract.

I used to use a PO box but it sat collecting dust for years so I don't bother anymore...I've had people find my personal residence by looking me up on the online tax records. 

I've contemplates selling and collecting what amounts to 10 years of profit at once.

Now house is done and you worked with an Agent or a Prop manager to get a tenant and you have a lease in place and have collected security deposit. 

Let them get a judgement and try collecting on it..ambulance chasing lawyers...forget it.

Allowing another investor/manager to operate your units for profit, while you collect consistent rent for 2+ years at least. 

For example, collecting three months of rent upfront helped you avoid missed rent, but even that could have backfired if they missed more than three payments.
