Do you plan on selling the finished home or do you plan to hold it? 

I would probably try to speak with them face-to-face or on the phone and finish the conversation by telling them you will send them a formal letter shortly with the exact date after you talk with your contractor/partner, etc. 

We purchased for $95K, we put about $50K into it, it's currently rented for $2500/monthHouse 2: We purchased for $95K, we put about $80K into it, it's currently rented for $3500/monthCurrently working on finishing the rehabs for the remaining two houses.This is our forever home family compound, so we have no intention to sell and hope to continue improving and creating new streams of income from the property.

It would let me finish that 12+ months sooner.relist option: it makes about 6% CoC but I am leaving a lot equity that I feel I should tap into.

Initially, I planned to finish the attic, add a bathroom and bedroom, and create a first-floor master suite, turning it into a 3/2.

Just finished up a project in Cincinnati. 

Likewise, the "Refinance" part of the equation doesn't assume you'll refinance 3 months or 6 months after you've finished fixing up the joint.

They finished one reactor (the years of constant transient workers staying nearby in RV's and mobile homes), but the majority of contracts are complete and they naturally go home.

New windows and doors, new kitchen, updated bathroom, new HVAC, new flooring and paint and finished the attic with flooring and heating/cooling.

Our total gut ran about $65k inculding all new drywall as the walls had an adobe style finish, plus we added two additional 1/2 baths.
