While the vetting of residents is greater with FF over an Airbnb or similar platform, I think Airbnb overcharges for the increased convenience. 

If you have access to some money you can increase your equity in one jump.

So spending 200k on an ADU will likely not increase your property value by 200k. 

But in smart buying, if someone has enough cash to pay cash for a property, they could easily stash a good chunk of that away to cover downed months and still leverage to increase the overall returns on their portfolio.

Something that is increasingly important to those clients is being cash flow positive from day 1 and this is what we deliver.

Quote from @Basit Siddiqi: I personally would not buy real estate with a retirement account.There are just too many headaches that are not worth the potential increased return.Some headaches when it comes to investing in real estate with a retirement account1) LTV values are less and harder to find lenders.2) Potential to sell or partially distibute the property if you have to do a RMD(Required Minimum Distribution)3) If you run out of cash and have to make a major repair, you may be out of luck and have to sell.4) Having to potentially worry about UBTI(Unrelated Business Taxable Income)I would personally invest in stocks/bonds/notes with a retirement account.I buy deals with cash and use a ROTH SDIRA so there are no RMD's.I buy at huge discounts to retail.
