If your parents are currently claiming owner occupant exemption, they would not be able to do this with title vested in a LLC.

We've sent a certified return receipt notice but it hasn't been claimed.

This takes away the unrealistic expectation to meet some made up metric.Flipping presents the perfect analogy: in any market either the front end or the back end is hard.

The last thing I'd want is two tenants claiming rights over a property.

It is being fixed up to rent right now.The land I have under contract to sell as is with a Quit Claim deed.

That way we could either claim expenses as deductions or through depreciation, rather than just as an increase in basis for capital gains if it was our primary residence? 

It seems to me sites like AirDNA and other revenue estimators for STR's seem to be giving me what I feel is an unrealistic number, my question is how accurate are these estimators?

. :)A claim like that is crazy...I personally think the fees that you signed up for is on the high side.You can view a couple a couple of posts on this message board about people signing up with 1800 accountant and then wanting to move on to another accountant.The thing with firms like 1800 accountant is that you will likely be with one accountant one year and then another accountant the next year because they have a high turnover.The issue with this is that you may have to re-explain your situation on an annual basis.Best of luck.

Many contain higher level ofchemicals (formaldehyde) and others compared to what they claim, especially per LEED standards.
