I've been at my current job just over 15 years and am eligible to retire in just over 10 years.

I’m in contract on a mobile home park that is eligible for a USDA loan.

I contacted the county who told me that it would be eligible for a tax lien auction as early as this July. 

If she went to Assisted Living - I can help you but it's only KS Specific - each state is different but I'm guessing some of the guidelines carry across states in regards to how she will pay for the ALF and eligibility for Medicaid and Home and Community Based Services (which is a medicaid program that would help pay for ALF)Anyways in KS - in for someone to qualify for HCBS/Medicaid to help pay for their care either in the  home or assisted living - you need to have less than $2k in assets - and consistently less than $2k in the bank - there is also something called a 5 year lookback period - I do not 100% understand how the lookback period works but will soon enough.So - as far as the assets are concerned - if your friends mother has the house and any savings there is no way the govt will be paying for most of her stay in ALF - and I also think it would be difficult to house her in an ALF facility for $3k per month - can be done but tough - Due to no estate planning the family needs to decide on what they are going to do - they will either need to sell the house now and just pay her money down at the private pay rate in a facility until she "runs out of money" then apply for Medicaid and go from there or see if the strategy of renting the house with her present income will be enough to cover the facility she's staying at.Individually the systems are simple however there are so many moving parts to Medicaid HCBS I've discovered in my time as owner of a facility I can 100% understand the families frustrations. 

I have been concentrating on buy-and-hold rental properties in more rural areas of North Florida and, to a lesser extent, the Ft Lauderdale area and I've seen the same thing:  Prices have risen more quickly than rents to an extent that it is difficult to find properties with the right fundamentals.  

Not only you will save on rent, but you may also be eligible for FHA financing. 

May I ask a rather fundamental question?

@William Springer, If that home in Brooklyn is her primary residence now then it's not eligible for a 1031 exchange. 

Im not approved for a loan but have been told I will be eligible in the new year once my next return is avail for review.
