I’m not sure all of the regulations/rules to this in PA though.

As for Alexandria specifically in terms of regulations don't take advice from a public forum - look up the laws yourself and make sure you understand them.

All of this said, be sure to do your research on STR regulations first and find a STR friendly location.

Great idea, but check your local regulations.

So you're going to have to do some research on the existing towns you're looking at to see where it's allowed and where it's not allowed.

3️⃣ Local Regulations: Before you invest in a short-term rental, it's essential to understand the local rules and licensing requirements.

It's important to stay informed about developments in the areas you're considering, as well as any potential changes in regulations or economic conditions.

I believe Hawaii will continue regulating STR and it will be harder to make the numbers work. 

Another huge thing to consider is laws and regulations, many times new investors will jump at Hudson county thinking the proximity to NYC is great for renting (which it is) but many of the municipalities in Hudson county have very strict landlord laws. 

Similarly, looking up deeds of trust, licenses, or other public loan documents, as is often recommended here, will only confirm that the company exists - not that you are speaking to a legitimate representative.
