I live in Minnesota but have a video editing business online so I can go anywhere and there wouldn't be positives or negatives to any. 

If you know of any online forums or organizations where I can learn from others and expand my network and knowledge on wholesaling or getting my first deal, I’d really appreciate any recommendations Thanks in advance for your help!

Some towns require a nightly online form to be filled out for any non-residents who are parking their cars (this is easily automated from an operational standpoint).As the MTR market becomes saturated over time, those who have separated themselves from the rest of the "competition" will continue to perform well by having an outstanding listing and all the MTR-specific amenities.

Take a close look at what other similar units look like on Zillow or other online listing sites and try and mimic them or exceed them.

Look at other rentals in the area and see not only how they are advertising or promoting online but also the inside and outside of the rental so you can create a similar environment to try to replicate the same results.

You can find them through local real estate investment groups or online platforms.Auction or Estate Sale: If the property has unique characteristics, especially being a large, old Victorian, it might attract specific buyers looking for such properties.
