I once had a foundation estimate that was roughly $8k different between two contractors, for the identical job.

@Joe VilleneuveGreat points Joe#3 Makes lot of sense when the interest rates are identical, interest rates have almost tripled now.#4 Transactional costs , depreciation recapture may add significant overhead

Airbnb will verify guest and host identities. 

Personally, for safety reasons (since the STR is also part of our home) I wouldn't list it anywhere else that doesn't verify identities or have a proven process for collecting security deposits, etc.

There are three main categories to consider:Confirm identityDo they pay their billsWill they maintain the propertyConfirming identity includes a government-issued ID with picture and knowing how to spot fakes.

In fact, Derek's link provided an equation almost identical to the one I provided.  

That one actually had a double identity...The stories I can tell!

@Daniel ChangThe appraisal for a refinance vs a purchase are two different things, even if the homes are identical. 

Ive also had lenders provide some information over the phone so long as the seller was on the line (3 way call) and was able to verify their identity. 

Arguably, these two ratios are nearly identical.
