I deduct washers, dryers, laundry detergent, soap, toilet paper, light bulbs, linens, towels and my promotional pens and adult oriented calendars.

Playa Del Carmen has A LOT of 2 and 3 bedroom condos since thats all the con developers were building during the boom days so studios that accommodate 2 people comfortably and 4 if necessary is what I think is the way to go.Regarding the vacancy rate - My understanding is that you can choose to use the calendar on AirBnB to show where you are booked or not and a lot of users choose not to because they are listed on all the other sites like HomeAway, FlipKey etc.But where do you get the 79% ?

The town of Ithaca has a lot of new str regulations, the biggest being you cannot rent a non owner occupied property (this is for properties not on lakefront) out for more than 29 calendar days in a year.

Yes, you can structure a Reverse 1031 Exchange whereby you can acquire your replacement property first by "parking" it with a Qualified Intermediary and then selling your relinquished property within 180 calendar days.

I'm going to put it on my calendar and was going to see if anyone wanted to meet up.

If you are buying and selling within the same calendar year, I am not sure how else you are going to avoid this being anything other than ordinary income. 

I was looking at Nerd Wallet, and they report 60 day processing and 55 calendar days to close.  

Regardless of whether you qualify as a "Real Estate Professional" for tax purposes (by having 750 or more hours of work in the field during the calendar year), your expenses related to the property should at least offset income from the property. 

Let's say you have a property that will take just a bit over 12 months to renovate and sell... now the rule for 1031s is that you can only use them if you hold the property for at least 1 full calendar year so does this mean that I can now 1031 the property or not?

3-A property acquired in August would require far more cash at closing for prepaid taxes versus the same property acquired in June of the same calendar year.
