So B2C is out, but perhaps B2B might be an option (e.g providing a streamlined solution for all of the major mortgage servicing companies for collection of payments.

If I reach out to a realtor, will they expect me to pay them to collect comps for me? 

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 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

It involves much more than collecting rent or throwing up a Craigslist ad every blue moon.

I have 2 sets of tenants that I have had considerable problems with collecting the rent over the past year.

Get the judgment and frequently the court personnel will instruct you on how you can collect.

The reason for this is there is certainly a lot of heavy lifting of resources required by a property management team to bring on a new resident including rent collection, setting proper expectations, accounting and building a positive relationship in the first month.As far as the quick re-rent of your home, I was hoping that would be something in which you'd see the value of working with us. 

I would say the cash flow would go up every year and that would usually be the case but my son will be moving into one unit probably for just the labor to rehab the last unit (collected rent will go down for a year).After that rehab is complete, at market rent I would have about $8k/month cash flow with underwriting that most would consider conservative (for example $1200/month allocated to maintenance/cap ex). 

My strategy as an investor has changed over the years, today I look at real estate more like a collection of properties and less through the cash flow lens.

You can find higher ROI (on paper) here and probably in other cities…but the probability of actually collecting rent significantly decreases.
