As far as the modification--I'm not sure that will be in a mortgage. That is another great question for a mortgage broker. If not, there are likely other programs available to help with specific modifications for your home.
Once you do get into a home, you will also qualify for homestead tax relief which will greatly reduce your yearly property taxes.
I know a great mortgage broker. His name is Reuben Rogers and you can call him at 864-787-9607.
Please feel free to email or call me with any questions you may have regarding Reuben or getting into a home. My email is email@example.com and my number is 864-884-6018.
I hope this helps!
