My goal is to keep this property long term, refinance in maybe 3 years when interest rates have hopefully come down and my property has also increased in value.Thank you for your help!

I think when one is starting out, you want to go lower than competition, but not so low that you attract the wrong crowd, so that you can build momentum and reviews.  

Over the next few years continue to buy a few more properties to build up the monthly cash flow then use the increased income to buy our acreage property.Our area is projected to continue to grow and appreciate fairly quickly so we are afraid of getting priced out of buying our little farm if we wait too long. 

If you were to partner with a great handyman/handywoman to give you the aesthetic finish and attract newer MH owners your way, I think this is an awesome strategy to build your own park. 

This will greatly reduce the cash flow to a point where it's not too appealing, even with a higher gradual rent increase by then. however assuming with continued 3% rent growth per year, it will eventually cash flow nicely again 2-4 years after the tax starts, assuming rents and expenses all grow at 3%.What do you think?

It feels like kitchen cabinets have increased insanely.

I'm sure you will attract a lot of visitors for the nearby colleges and hospitals.I would reach out to some hard money lender brokers like Sherman Bridge, that will give you access to many different HMLs at once and you can easily compare their rates.A good local HML is Chris Misutka, I will DM you his contact info.Most HMLs can close within 2 weeks but they may require an inspection.

All of the above going well: Great job, but if you're getting blown up with requests and showings and applications it means you probably priced your place too low and you should consider increasing the asking the next time. 

Good opportunity to increase income and boost returns as seen in my data.

In fact, when rates decrease, it often stimulates increased demand for homes as more buyers enter the market to take advantage of the lower borrowing costs.
