Your first duty as a potential homebuyer is deciding if this is the right time for you to buy a home.
Unfortunately, this can work against the homebuyer, who will be forced to pay a higher payment and more interest if average interest rates climb.
Most programs define a first time homebuyer as someone who has not owned a home for a certain number of years prior to applying for assistance.
It is preferable to explore an FHA or VA program if you are eligible before looking into first time homebuyer programs sponsored by lenders.
Another option you may be looking for if your search is for "Midland Zero Down" is the Homebuyer Assistance Program (HAP) through the city of Midland, Texas.
