., which is the closest I can to Camp Pendleton, where I am stationed.

Even then I would be hesitant because people camp with RV's/tents at Oklahoma state parks before they would get an Airbnb. 

The tenant is having trouble with unauthorized day and overnight parking, as well as homelessness, drugs, etc.

The team is based in Bolivia, Argentina, Honduras, and Pakistan.All agents are paired with a supervisor and trainer to offload a lot of the day-to-day responsibility and management from the operator's sizeThe agents help operators set up a 24/7 front desk team (Guest services/communications), manage overnight emergency shifts, create and optimize listings, revenue management, dispute negative reviews, manage Airbnb claims, in-house vendor management, bookkeeping & sending owner statements, manage collections, digital marketing, and other back-office tasks.Nonetheless, happy to chat.

Cruise terminal may help with overnights but downtown sucked.

Given the details here I'd say no, you should take any development thoughts off the table because to do that is not something one simply learns over night, there is a lot to it. $209k is very cheap for 40 acres, so that offer could be a person interested for hunting land and nothing I'd get excited over, and I wouldn't assume it means anything other than you could sell it for $209k.

Most HELOC's are based off prime and these are consumer based products (rate determined by margin which is fixed + prime).However the commercial departments in many of these banks or credit unions offer fixed lines on their commercial interest only products that can be based off different indexes like CMT (contact maturity treasury), SOFR (secured overnight financing rate), or other indexes that are less volatile than the prime which is directly linked to the fed funds rate + 3.00%.This is why the fed funds is at .50% right now and our prime is currently 3.50%.Just make sure to pick a product and index that works with your overall strategy because in between deals you'll be carrying the "equity," you used to buy a property on this line most likely.
