It is very important to understand that contacting a “professional” to learn how to do this only results in them trying to sell me crap properties (whether high end or low end). I’ve tried contacting realtors out of state, and they attempt to sell me crap or someone else’s problem. No one has a vested interest in actually helping someone or teaching them about how to get an out of state rental. very frustrating. I could go out tomorrow and buy a rental in my city, but that is the last place I want to own one. Anyone? Are there an real people on here?
Refinancing may not be worth it to you, depending on your situation and interest rates, but maybe a reverse mortgage is just what you need. It's typically an option well worth considering for those in or near retirement. A reverse mortgage is essentially a loan, with the amount borrowed not having to be repaid until you die, sell your home, or stop living in it (perhaps because you moved to a nursing home or died). At that time, the home can be sold to cover the debt -- or your heirs can pay it off and keep the home. Reverse-mortgage income is often tax-free, which is another big plus. The amount you get can be delivered in monthly installments, providing very passive and reliable income in retirement.
For a person working for a wage, their source of income is their job, or their labor (aka their time that they sell to someone). But you can own a house, and rent it out, and when your renters pay you renter every month, the source of that income check is your rental property, or your house. It would just be called rental income. If you have money in the bank in an account that pays interest, those interest payments are another source of income. We can say the source is interest payments, or we can identify the asset that is generating rent, and say your money in the bank that is generating “rent” (aka interest) is your source of income.
