Let me do my best to break it down into bite sized chunks.1) Your property tax increase is going to be 2% of the original assessed amount that breaks down to be .024% of the purchase price.

@Micah Huffman unless you are going to commit to learning some basics about being a landlord AND are willing to commit at least 2-4 hours each month managing a Property Management Company - it's probably best you sell.Otherwise, it's highly likely you could lose more due to bad tenants and management.

You'll improve over time, but this basic formula remains.1.

It would be a good idea to assess your tolerance to risk and then plan something like that, but using a heloc is going to be around 9-11% in this market so to pay something off with lower interest rate to borrow more might not make much sense.

Also , I would love to connect with any agents who specialize in STR market in Boston Mass area. airdna is pretty accurate . lenders use it to assess rental comps for short terms rentals when financing a short term rental  I use it for DSCR loans as well; it is accurate yet conservative because it gives you the median 50 percentile for the area based on comps.
