IN any case, I would send a certified copy of the new terms to the Housing office along with same copy to the resident; Then I would confirm with the Housing Authority/Resident they received the letter & acknowledge the new terms.

But, I do like you having reserves when starting out. 

TSAHC's down payment assistance programs can be great options to assist qualified homebuyers get into a home that they might otherwise not have the available funds/reserves for.There are also a few other down payment assistance programs here in Texas as well that are worth mentioning:- TDHCA (Texas Department of Housing and Community Affairs) offers the Texas Homebuyers Program with a couple down payment assistance programs. 

It's been a crash and burn learn process but I still started getting reservations within 2 months and a LTR that will be with me until next year. 

Reserved the land but then now knowing what to do, gave away the option on 1st

Reserves are key.

I would recommend someone with an existing mortgage look up there own address for confirmation. 

Always, always, always have a reserve because there will always, always, always be unexpected costs.HOW MUCH TO RESERVE?

Conventional loan, excellent credit and reserves, nothing owed on the property and the property is seasoned.
