Made a good sum from the sale.In hindsight, I wish we had instead rented it out. 

It was an investor who'd bought a sfh with some land, rented the house, and then partitioned the land as a small RV storage.

I can guarantee you Fed Chair Jerome Powell took a deep sigh when he heard about this proposal from the Administration.

The property is rented by DCFS ( department of child and family services) a government tenant and are occupying the building for last 30 years and have no plans of relocating.

: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+, 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, 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.

It has only been rented for 4 years of the 8 years I have owned it.

The question is, how do I go about asking for the lost rent?

I've talked to a few agents in Memphis, and the impression is that vacancies are up, rents are down, but prices ARE NOT trending down? 

And when you market your home for rent...if the other properties are at the same price but look better than yours...that means they will rent first. 

They can pay you market rents because of the co-living (renting room by room) approach.
