Our house is small so my parents can't just move in with my husband and I. We got an estimate for an addition to our home so that they are close to use, but it still offers some autonomy for my very private mom. Dad has a brain injury and dementia, plus has chronic pain from falls. Mom has MS and debilitating arthritis. We need financial help to make this addition. We can't go the bank route for a myriad of reasons, but we and my parents could pay a small loan amount if there are agencies, investors, programs, or whatever is out there to help in this situation. I'm not even sure where to look. Any ideas?
I'd also consider, as some others said above, that your parent's medical conditions could progress to the point that you would not be able to keep them in the home, especially, if they needed skilled nursing care.
Have you considered converting a den or living room into a bedroom for your parents? It's not ideal, but, it would be low costs. Of course, you still have the problem of needing wheelchair accessible doors, bathrooms, shower, and room for caregivers if some outside help is needed.
One thing to remember is to look into the future. With your parents medical conditions as you know it will only get worst. A year or two your Dad might need either in-house caregivers to help him, or be moved to Assisted Living/Memory care... same with your Mom.
If either or both need to go onto Medicaid, Medicaid will notice that your parents had paid some money into the addition, and that could throw a monkey wrench into your parents qualifying and monies used by Medicaid for their care.
Oh gosh, there is so much to think about.
If for what ever reason you can't get a bank loan, I suspect there may be some credit issues, or perhaps house standard issues (i.e., house isn't up to code). That's not a criticism, just a concern. If that is the case, it could be hard to find a lender.
The VA does offer some help and loans for retrofitting, but someone in the family would have to qualify. I doubt if you could find an investor; they're going to look at marketability and what they can get out of the situation.
Counties sometimes have home improvement loans; check with your local county.
