You can go to
HUD.gov
And ask for your State, Pennsylvania.
and you will see they
do have adjusted low rents for senior apartments, in many locations in your State.
They also have programs for home owners to help with home repairs.
You could look at either option, on that site,
OR even better for you, would be for you to contact any local agency near you, (a town or city office, or a senior services center)
and ask them for a list of the HUD-assisted Senior apartments closest to you, preferably in your area,
that you could find out exactly where those specific ones are,
their neighborhoods, and about their wait lists.
That same local town office or agency,
you can also ask for info regarding any/all possible help programs for your home, if you were to try to stay in your house.
You might also try
pa.gov
and look for Senior info, there, to look for both types of options, including low income apartments , and/or, home repair help programs.
