I could have hired a pro, completed the work in under 30 days, and then collected five months of rent, which would have paid for the contractor and freed up my time.I learned a lot from the experience and don't regret it, but I'm aware of my limitations and more selective about what I take on. 

I am fully aware this is not a legal advice forum, but just looking to hear what other landlords have done in this situation. 

Yes, it was the penalty I paid for not being firm and not knowing what do to...it seems like alteration request being used as way to get more refund is not new issue, and until Airbnb fixes this hosts have to be aware and plan for the course of action and stick with it.

Just be aware that upfront costs can be higher, and returns may take longer.

However, be aware that the IRS closely scrutinizes REPS claims, so ensure meticulous record-keeping and documentation of hours to substantiate your status.

I was aware of zoning regulations but had no idea the taxes associated with STRs!

I'm not aware of anyone in the US who will lend against collateral in a foreign country (not saying there aren't, I just don't know of any).

We’re aware of what Plymouth looks like on the construction costs.

Because it can really make or break a deal, especially if you are not aware of the true cost.Good luck, and feel free to contact me if you have any further questions

Not really expensive, but just be aware you will need it along with your short term rental policy.Those are just a couple of things I can think of.
