I second Transunion as a decent screening tool.

Someone that is more aggressive, may want lesser even though skin in the game.

And yes, any decent PM company should have relationships with reliable eviction attorneys.

You have decent cash flow that you'll continue to accumulate, which you could put toward a deposit later for another property. 

My strategy (at the time) was to aggressively pay down my mortgage, and the recast allowed me to reduce the monthly committed amount.

If you don't want to be as aggressive you can pay just want your PMI payment was towards your HELOC and still save quite a bit on what many feel is wasted money for the mortgage payer.  

Knowing that if you find a deal that the team is looking for, you can get it off your plate quickly and make decent money.

house in decent condition . no application / no interest so far.is that make sense?

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

Assuming these are in decent areas, this is the best solution.
