With land investing/flipping becoming more democratized/accessible  (so many landed courses, tools, resources etc), current prices/RE trends etc, is it still worth getting into land investing/flipping for a brand new RE investor ?

That will probably stop the problem.Their lease ends in a month, so there's no need to evict.

The idea would involve working together to construct a road that provides access to my property.From there, I’m considering developing a 16-unit multifamily project on my land.

We were forced to call police & provide them with a 'Cease & Desist' in an effort to stop the harassment.Our attorney has advised that we do not engage with them in any manner.

Yep, off water, but with nearby water access and view seems to be the same ROI considering the cost of the property.

I wrote a letter to the HOA yesterday explaining why the door was needed, how security would be very tight, and how the HOA itself could potentially be responsible for any ADA fines/penalties if they are found to the "barrier to access" for ADA as they control the lobby.We have a tenant lined up and obviously this is causing a major issue. 

Nothing illegal about doing that, but if caught, the lender may call the loan due and if you don't correct the situation or pay the loan off, they willstart mortgage foreclosure.3) You could also go the HELOC route to tap the equity in the home, but the 12-month owner-occupancy will also apply AND the interest rate on the HELOC will fluctuate with the Fed Fund Rate.4) You could do a cashout refi as an investment property, but that will be at an interest rate 0.5-1% higher than owner-occupied rate.Suggest you meet with 2-3 lenders to explore your options about the above.Once you have access to funds, recommend you buy a 2-4 unit with 20-25% down. - You can buy owner-occupied, live in one unit, and fix up and rent the other unit(s).- If you're handy, recommend buying a property in the worst condition you can tolerate.
