So here's my scenario: I come to you and say I want to see a particular listing.

This is the second time Ive heard consideration to renting to one ethnicity on BP which alludes me to believe it may be a common mindset.

This is the commonly selected option on the contract and this of course is decided BEFORE the contract is signed. 2.

Your risk is lower in this scenario, and trying to squeeze BRRRR and flips in this market is tight and risky.

What you wrote would be ideal scenario.

I hope this provides some clarity around the refinance scenario.

Triple Net leases allow the Landlord to pass Operating Expenses (primarily comprised of Property Taxes, Insurance, Common Area Maintenance, Snow Removal and Property Management) directly through to the Tenants of the property on a pro-rata basis. 

Would sec 8 decrease the rent to the calculated fair market value of rent or at worst case scenario remain the same and sec 8 decline the increase?

You need to talk with a lender about your particular scenario before pulling the trigger.

In the beginning its common place to take debt under their name to start off.
