All,Based on your experience, would you say, that the real estate tax for a vacant land should be correlated with its usable part? 

You need to find off-market deals and preferably direct to seller. 

For example, are there more tax deductions for doing a BRRRR? 

NO GREAT DEAL ONLINEI keep hearing that "only off-market deals are great deals."

I have heard anecdotes about how doing a quick claim deed later, the county might consider that a sale, and re-evaluate your property taxes.

Time blocking - The calendar is set up in 15 minute periods, but most of my day is blocked off into large chunks of these periods. 2.

My #1 goal is still to find potential off-market deals, but my #2 goal is to secure listings.Would it be viable to advertise both cash w/ fast close and listing services on the same mailer? 

This may be more of a question for a lawyer, but from a tax perspective, that's my input.It's also worth looking at the sec. 121 home sale gain exclusion to see if it might be something you qualify for in order to take advantage of the exclusion amount since you mentioned it was a previous primary residence.

@Gladys Villa we chose to buy a fixer-upper in a great neighborhood, live in it for 2 years while renovating, sell with the tax exemption (now up to $500,000 profit tax free), then repeat until our kids needed more stability for schools.

I'm not a tax specialist, but I believe there would be a way to rent out your entire place while your're away on contracts.
