Is there more long term appreciation possible if you hold the units longer?

I would never do sub to for the purpose of holding long term rentals  ( at least personally) .

I can only imagine that they got a bunch of big time investors and business loans to grow this out.

At the end of the day its about price and terms. 

Buyers could look at a DSCR loan which does take into account the revenue from the rent but it doesn't count towards the value of the property.Now, buyers could look at a business loan of some kind but I am not sure they would qualify if it is only one property and even then, the value is mostly in the property and not the possible revenue. 

The Property will be a good long-term investment whether you do the dig down or not! 

The best amenities for Airbnb in terms of ROI often depend on your target audience and the location of your property.

The two are almost entirely different markets in terms of price points, returns, tenant quality, and overall investing strategy.

She can use that money to get a hotel room or short term rental....or stay with family or friends.
