He knows the areas that you can legally air bnb, what specifically the property is going to need to maximize bookings/ROI, and has the property management contacts to optimize the ROI. 

I did better than collecting rent. 

The rest have a combined worth of about 1.5 million but aren’t owned free and clear yet.All Properties are collecting rent and generate about $16,500 (profit) a month in Cash flow after mortgages/expenses.

I’m currently facing a similar situation and realized that I wasn’t using the right resources or consistently marketing to a single, optimized list.

About 4 years ago we purchased a retail center for cash and after stabilizing the tenancies financed $650,000 at 4% fixed 20 years with this lender.  3 months ago this lender allowed us to wrap their note in a new first lien we provided to a buyer with a 10% interest rate - essentially granting us the right to collect the differential between 10% and 4% on the principal balance (currently $610,000).  

If I hired a PM that would also take care of collections (among other things) would I still need a service like rent redi? 

During this year, I've experienced inheriting a crooked property manager I let go on day 1 that tried collecting rents from tenants weeks after, an eviction (same person) and a successful lawsuit against a non performing seller that backed out the day of closing. 

Avestor is another company that's offering these combination of investment to be available while they would collect another layer of commission. 

You can collect a finders fee. 

I recently evicted a tenant for non-payment and non-confirming the lease rules, and would like to file collections against her.
