Does this exemption amount get subtracted from the sale price of the property, or the assessed value of the property? 

This helps in making better investment decisions and assessing project feasibility.

Once we got the home reclassified at the 4% rate, the taxes dropped to under $600 with the same assessed value of the home.In my experience, rental property tends to be taxed at an actual rate of 6% while owner-occupied property has an actual rate between 0.5 and 0.7%.  

But the insane tax increases in Jackson County, Missouri (Kansas City) were deemed illegal:"Missouri’s State Tax Commission ordered Jackson County to roll back its 2023 property tax assessments, which raised homeowners property assessments by an average of 30% and more than 100% in some cases.

The reality is, rising property taxes, maintenance costs, increase insurance premiums (I'm a broker so don't get me started here), an HOA assessment or annual increase, etc, etc, etc.

I'm currently considering whether to 1031 a couple of rental SFH's I have in the DFW area over to Vegas.Having lived in an owner-occupied house here for 3 years now and looking at my Clark County bill:- The assessed value is only 25% of the current "quick and dirty" market value (Redfin, Z)- There's a line item where property tax rate appears to be 3% of the assessed value- ... however, another line item subtracts a lot from this because of the lag from owner-occupied increase cap percentage of 3% annually (if I'm understanding correctlyAlso, despite changing hands 3 years ago, it's interesting that the assessed value didn't get re-assessed to the purchase price back then.

I don’t have any XP with the Berkshires, but I would agree with your assessment of there potentially being more to do in the summer.

I would advise you to look for a house instead of a condo.Condos have many fees, rules and can have expensive assessments for repairs and improvements that you will be forced to pay.Also Condos are a dime a dozen so the competition is fierce which drives the nightly rental rate way down.

I was able to withhold less from my W-2 income in anticipation of these savings, providing me cash flow in my pocket each time I got my paycheck.It could be beneficial to engage an accountant to help you assess the cash flow and determine if you are maximizing potential cashflow derived from taxes!

If the cash-out refi provides liquidity and good terms, it could be worth taking, but make sure it doesn't interfere with your construction funds.I can help you assess both options and see if we can offer a more favorable solution.
