I have been my father's POA and his caregiver for over 4 years can I keep and live in his home if I pay reasonable amount of rent---also-If I do repairs to his house with my own money---can I be reimbursed for the repairs if Medicaid decides to take his house for reimbursement of their expenses. Or is there a legal document that can be drawn up to make the house legally mine if I continue to live it in and continue to make repairs. thank you.
Some states in certain instances may let you keep the house outright. Other states, from what I understand, may grant a life estate, where you can use the house as long as you remain in it, but it reverts to the state if you move.
If Dad is competent he can set up the Medicaid planning for you. And even under Medicaid recovery, many times they will allow the child caregiver to remain in the home.
MERP has all sorts of exemptions, exclusions, hardships, etc which family can file for. It is up to you to do this and to provide whatever documentation is necessary. There is a caregiver exemption, in which if your provided care for 1 -3 years (depends on state) that kept them from going into the NH, then you can file the caregiver exemption. So MERP does not do a claim or a lien. There are all sorts of other exemptions too and in some states you can do certain types of deeds or life estates which will be outside of probate so outside of MERP. Each state manages Medicaid uniquely so you need to google your state's program. It can be overwhelming to figure out and really working with an elder law attorney can be the best way to deal with all this.
Renting the house, well, that's probably is a cluster to deal with. Rent of any type is income, and all their income has to be paid to the NH. Plus there are tax filing stuff on rental property and it could totally change her homestead exemption. Probably no advantage to paying rent unless the rent is huge, like 5K or so, and can be enough to totally private pay for her care. I doubt that is the type of rent you were thinking.
But it's good that you have the income to pay rent. Realize that once he goes into a NH and onto Medicaid, all of his monthly income (SS, retirement or any other income) has to be his co-pay or her "SOC" (share of cost in Medicaid speak) to the NH. He can continue to keep home as an exempt asset for Medicaid but will have no income to pay for anything on the home. If you are living at the home, and want to stay there, you will need to pay for everything on it. Taxes, insurance, utitilies, yard work, repairs, etc. And you will pretty well need to pay all this from now till whenever dad passes away. Try to go though the past couple of years to see what the costs on the house runs and then look hard to see if it is manageable for you to pay for all the next few years. If your state does the caregiver exemption like most do, you cannot file for it until the elder dies and then you submit the exemption after death upon the state's sending you the MERP "intent to file" (a recovery claim or lien) letter. In order for all this to work, you just have to have the disposable income to pay for whatever on the house for the unknown period of time that dad is still with us and then file the exemptions and the documentation for the exemption.
For a lot of families, paying for things for their parents home just isn't feasible in the long run. So they end up placing the house on the market within the first year @ the NH and then all the $ from the sale has to be used for a spend-down at the NH. If you can't afford the costs on the home, you probably are better off selling the house from the get-go and doing a spend-down of the $ before ever applying for Medicaid so that you can get things that dad will need - like dental work, a funeral / burial policy - rather than just paying it all for his NH stay. Good luck.
