The LLC formation combined with operatring the company in accoordinace with the operating agrement & appropriate funding to present itself as a viable business is what's needed.

Im sure this has been posted before plenty of times, but I just got back into real estate investing, and I am looking for a good website builder option like Carrot, or any other, that you guys can suggest. 

I would love to find a software to help automate the following tasks, there are lots of options, most at $40/month, would prefer cheaper but will probably pay this for the best software that can best handle:- creating a direct booking website from my Airbnb listing, I know some websites have an auto-builder which would be preferred- handling automated messaging- handling calendar and payments, including add-ons- sending agreements and collecting and returning depositsI am overwhelmed with the options and suffering analysis paralysis. 

There are some great options out there right now for cash out refi's.

I believe, aside from house hacking, a LTR as your first investment is a great option since it will teach you many different aspects but not deal with the headaches of a STR. 

What are the best financing options for this?

Selling the rental property within the next three years to avoid capital gains tax could be a viable option if you're concerned about tax implications and don't see significant benefits from holding onto the property.

Take into account variables like affordability, property taxes, rental regulations, and vacancy rates while doing in-depth market research to find viable investment areas.

It seems to me you have three viable options at the moment.1) Non-renew. 

Look for other types of renters who aren't necessarily affiliated with hospitals or go just outside the neighborhoods immediately surrounding the hospitals and market it as a good option.
