Easy answer: put all of the properties into a revocable trust, hire property management, and decide how the income will be divvied up now and in the future when you pass. 

The existing owner usually gets a 10% down payment that is non-revocable. he will provide the financing loan on the sale and charges a higher interested because they have already failed at a bank. 

I've found the parcel information, and the house is in a revocable trust.

I'll sign a deed removing the property from the LLC at closing and then put title back into the LLC after closing (with full consent and no risk of triggering a due on sale clause). 

When you run a background and credit check (you need to get written consent to do this), it's based off their SSN, not driver's license.

My mother has her own revocable trust (after I nagged her enough to ask her lawyer)  which has the two condo's and property in Doylestown in it.  

Based on Article 16(Specifically 16-3)"All dealings concerning property exclusively listed, or with buyer/tenants who are subject to an exclusive agreement shall be carried on with the client’s representative or broker, and not with the client, except with the consent of the client’s representative or broker or except where such dealings are initiated by the client.)" of the Code of Ethics.Personally I have never called the board or filed a grievance so that is not my stance.

The advantage of this method is that the tenant knows exactly what you see and the landlord is not in the middle of consent or compliance to credit reporting laws.

So before the applicant even signs the lease, I would need his/her consent to have a copy of his/her key to the unit; and if i don't have that consent, can I deny that tenant the unit and pick another applicant who's more compliant?

However, I do always let my client know when they've asked a billable question and make sure I have their consent before I start work.I think what happened for the OP is that the questions were becoming too frequent and too time consuming (in the CPAs mind).
