I understand each city/county may have their own permitting requirements, fees, regulations, etc. but I'm wondering how people are making any return on their investment if it maxes out at 90 day rental.

A heavily regulated market.

The City does not currently have regulations or allowances for land use known as “short-term rental.”

Are there any local regulations or processes that are particularly tricky to navigate?

If you are in a metro area, I would always make sure it works as a LTR as a worst case scenario that regulation shifts.

Personal residences or properties primarily held for personal use typically don't qualify for a 1031 exchange.Understanding state-specific regulations for like-kind exchanges is crucial.

New airbnb regulations obviously, but anything else? 

Lastly, don't overlook any local regulations or HOA restrictions if any.

Hi All,Question for you pros, and maybe I'm thinking too deeply on this, but does Dodd-Frank (or its attendant regulations) set any restrictions on purchasing mortgage notes, or only on loan origination? 

Congratulations on your inaugural post – it's like your first step on the moon, but with less risk of tripping over a rock and more about not tripping over real estate regulations.
