Local investor agent here.

We’re working with a local agent, just published it recently in the traditional platforms (StreetEasy and Zillow), and looking for additional ideas.Hit me with your best strategies!

Don't rule it out, happy to put you in touch with local NYC lenders that can make the deal work based on how much cash you want to put out. 

I'm also looking to network and connect with more investors locally, so I'll shoot you a friend request and maybe we can link sometime.

Check out my page & let me know if you have any more questions or need any help here locally. 

According to the local realtors I met with, the market here is very hot with little inventory.

I am from California and I am looking to get into the local market.

Each of them sought the property for their primary purpose of worship/office/etc, and then sought out additional uses as well - nursery school, food bank, place of worship for a Jewish congregation (Saturday versus Sunday), auxiliary space for the local library that needed additional educational space, counseling, etc.There is merit to your concept, but many factors come into consideration:  zoning, parking, how easy it is to "convert" space, etc. 

Also not all houses would make a great STR, so getting local advice on location, size, etc would be beneficial.
