All options must result in an immediate quit claim deed.I have come up with the following possible scenarios.Option 1: Somehow convince the bank to do a loan modification to remove her former partner from the mortgage (with his permission) by agreeing to a 1% interest rate increase.

Architects and engineers aren't builders so there are always slight modifications that happen on-site.

If they fail to PAY the increase, the now owe RENT, which you can then charge your late fee on, and/or initiate the eviction process.I always provide options with the renewals- "Tenant agrees to new Terms"; "Tenant will vacate within (number of days per local law)"; or "Tenant proposes modification to terms, subject to review and approval by PM".

ALTERATIONS: Tenant agrees not to do painting, wallpapering or structural modifications to the premises.

This idea is on the cutting room floor so I’m open to any and all modifications.

Acquiring B-class and, ultimately, A-class properties, necessitates increasing equity and building a reputation.

Most have 10/20yrs to build a portfolio, and that necessitates leverage to maximize potentials. 

So far as I can tell, pretty much all traditional mortgages, as well as down payment assistance programs and low income grants, would both disqualify me based on the debt/income that a mortgage would put me at, and necessitate my occupying any purchased real estate as my primary residence. 

.- Permits from the county to do any modifications need to be pulled by a contractor, making repairs more expensive ( Down here a homeowner can be its own general contractor and use subs to do the actual work).

@Sada Rafi I just give them a 1 page addendum that says they are renewing the lease for xxx time period and what the modifications are (usually none, but sometimes things get tweaked).
