I think if you want to do a traditional rental remotely a good property management team is key.

It does require self-employment activity, but has a lot of advantages: Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe, though it's best not to utilize this benefit :)

I will be putting my primary residence on Airbnb for 3 months while I'm out of the country for work.

Even RMDs from traditional IRAs can be tapped.Does anyone know if there is a way to protect these funds so my mother doesn't become a pauper taking care of my father, then is destitute if/when she needs a home? 

My only nest egg is about $60K in equity in my primary residence.

I am about three years away from paying off my primary residence through a savings plan of money I'm making from my job/side hustles. 

If he is looking to finance a deal the traditional way, he will need to quantify his monthly debt obligations and make sure he will meet the criteria for the debt to income ratio for a loan.

Does anybody have any advice on finding the right hard money lender or anything outside traditional institutions?

We have 3 separate entities that are held by this primary holding company and the tax prep fee proposed is $12,800. 

I've looked into umbrella policies but because our primary residences are in NYC and not PA, some companies can't offer it to us.Thanks for any insight!
