Look up Pace Morby and his groups, etc, they sometimes source homes that don't have as high of an entry fee as buying a home the normal way would. 

What is typical? 

Perhaps tax credits or even lower tax rates at the Federal level for a builder to build and sell homes of certain sizes or price points. 

Typically this is a requirement with most lenders.

There are other modular homes in the area, but there is no info about them selling on the MLS to use as comps, I'm assuming this is because they were just purchased as a lot and placed a modular home on it.

I bought my first home with a VA loan back in 2020 after my deployment and that purchase has lead me right into real estate with using my equity to buy my 1st property and then on to building a small portfolio.

AirDNA states: “Average yield is calculated by dividing the average annual revenue potential of short-term rentals in proximity to the national park by their average home prices obtained from Zillow.

Also, what other platforms are people using for rental price comparisons and have you found them useful/accurate to help you rent your home in a reasonable amount of time?

One flip I did, I priced with the comps but they were about 4 months old and the market had already went down so the home ended up sitting for a lot longer than I would have liked.

Typically, if one condition can't be met "The usual way"... there is another way to meet it.
