We embrace S8 applicants, but screen them just like any other applicant.Many have an entitlement mentality and try to leverage their S8 voucher by pretending to be helpless:1) A percentage won't apply because they expect a landlord to waive application fees for them.2) Many cry broke and expect a landlord NOT to charge them a security deposit.3) Many of those same S8 tenants trying to avoid paying a security deposit, won't make an effort to call the list of nonprofits we send them that will pay their security deposit if they apply.4) A lot of them try to avoid paying for utilities.

The only good use I can see of the fees are based on rent charged would be for a tenant to purchase it and charge themselves $0 or near $0 rent to avoid the rent based charges. 

This allows you to keep more money working for you in the real estate market, potentially helping you grow your investment portfolio faster.

Maybe bpers could unite on this and get another PM in mass faster?

There are many ways to get around it, faster than it kicks in.  

I’ve had great experience with private landlords in the past, and have found fellow pet lovers that didn’t charge pet rent, or accepted my larger dog (when he was alive) to live in an apartment without hassle.

As far as ethically that is part of my nature and I don't care for the aggressive (potentially predatory) strategies discussed by others, but I see value in offering a transparent and convenient service with lower costs and faster turnarounds than traditional MLS transactions. 

Then I wrote 3 books, became the person in charge of education in my REI and had to produce presentations every month (at least 2) for it, and before I knew it,...It's not as hard as you think, at least it was for me. 

Some of these bookings we get through marketing partners who build these relationships and charge referrals fees for finding the housing.

They can separate themselves from traditional real estate investors by building a robust EIN Corporate Credit ("Ever-Increasing") investment infrastructure that allows for faster portfolio expansion and more sophisticated financial maneuvering.
