My question @Val Jaz is did the tenant not raise any flags or concerns during your screening process? 

Get a good lease, learn to screen tenants well, follow the lease.

You can negotiate a commission/rate for their time, but they don't have to be involved in management or even the pre-screening.

I can't say that rents will be automatically  entered, but they help with scheduling, tenant screening, repairs, accounting, etc...Buildium, Yardi, appfolio are a few. 

The low income element, with SEC 8 or not, makes screening harder, maintaining harder, and collecting harder.

I can’t stress this enough screen your tenants !!!!

My fear is that he leased up the building with low quality tenants and doesn't want me to review the tenant screening materials. 

The purpose of screening is to find reasons to reject applicants not find reasons to accept.

This allows me to compare a property that I'm looking at to similar properties (location, quality of finishes, size) in the area.

It takes less than 2 weeks to find a qualified tenant and process them through a rigorous tenant screening process.Even in situations where there will be some re-painting and some renovations, the tenants are just happy to find a secure, good apt in a safe and trendy neighborhood.When I build my Business Plans, Vacancy cost is projected to be ZERO in my investment localities.If a friend or relative invests in a different location, then I look at the asking rent versus the Fair Market Rent (FMR).If the asking Rent is approximately the same as the FMR, then, depending on the vacancy rate of the target area, I would estimate 1 month vacancy allowance.IF the asking Rent is significantly below the FMR in a highly dense locality, then there is no point on adding a vacancy of any significant value.I once had an apt with a FMR of $3k per month.
