Many times, however, tenants "go bad" and once they know they have passed the 12 month test, then their good behavior might wain a bit and you are stuck with them. 

1) A down payment up front of $15-$30k per property (or whatever they can afford that you’d accept). 2) Rent (not applied towards purchase) - covers your mortgage, but no more maintenance or management fees, etc. 3) A windfall of the balance of the purchase price at the end of the term.Bonus: if they want, they can apply additional funds towards the balance of the purchase price on top of rent. 

Do some interviews, maybe a test cleaning to see how they do.

Often what they ask for is not what is always required... it likely says something like "Verify the duration the entity has been in business" and someone decided "A letter from a CPA would be acceptable and easy".  

I have heard the same but also have never had to test it.

We are considering renting a home in the neighborhood we are interested in buying in, to test it out for a few years.

Additionally, be aware of any specific requirements or regulations related to accepting vouchers in your area.

Same reason why an agent may push a seller into accepting $10k less on an offer, it gets the house sold and the difference is only $300 to them (based on 3% commission), whereas it's $9,700 to the seller. 

Hi Kayla,If the seller accepts your offer then the offer is contingent.
