What vehicle can I set up to hold this money so I avoid cap gains tax?

If its better spent elsewhere then you may want to reinvest or redirect that money into other vehicles with comparable risk (not saying you should go full speculation or full spec like Cypto's, building spec homes, or something you have never done before, etc).The other way to look at it is if you pay off that 3% note or mortgage you're in essence saying that you're accepting to save 3% annually or .25% per month (X12 months = 3%) effectively rather than investing it else where.

What Charlie said plus factor in all the expenses the agent has such as gas, vehicle maintenance and insurance, health insurance, E&O insurance, desk fees, MLS fees, Realtor association fees, marketing, cell phone, etc. and they’re almost certainly losing money on this transaction even with the $800 added on.

As long as you don’t rent it out, you do change your driver’s license, your banking info, your  health insurance, your car insurance, mailing and voting address.

Underground power lines are typically pretty reliable and aren't at risk of having trees falling on them, or being damaged by strong winds, long term exposure to the elements, vehicle accidents, etc.

@Michael Hyun We wanted to make our Costa Rican Family and Corporate Mountain Retreat a unique stay so we bought a property with amazing views and then added these features:- Art on the walls by local photographers of beautiful places to visit in Costa Rica- Pick up and drop off at the airport plus vehicles for rent onsite- Authentic Costa Rican meals cooked by our grounds keepers- An exercise room with weights, a treadmill, and an exercise bike- and tour guides that can take our guests on excursions.

Okay, I said one thing, but after reading that you are into auto tech, also please get as knowledgeable as you can about electric vehicle and hybrid vehicle repair/maintenance.

We are looking for a lawyer to assist us with a shared driveway issue where the neighbor has parked broken down vehicles on the driveway and a mobile car cover that is preventing us from working in one side of our property as well as accessing our backyard.

You say passive income is the goal/driver for keeping it but it sounds like you're not passive if you have to advertise this much.

Concentrate on IRR and look at real estate as a 7-30 year investment vehicle.
