I'm trying to decide between building an Accessory Dwelling Unit (ADU) on my existing property (secured permit) and investing in a rental property in a cheaper market.

This is a great time to look into the New York multi family market.Brooklyn has seen the highest percentage increase in inventory (74%) compared to other NYC metro area counties since last year (source: oneKey MLS). 

I would suggest calling Hillsborough county tax collector and ask about appealing your taxes and you will get directed to the right place.

Back when I was brokering commercial real estate 100 years ago I had a deal on a small office building fall through when during the walk thru just prior to closing the buyer insisted on checking the candy vending machine and verbally to;d us and sent us a follow up letter informing us that he wasn’t going to close because the Baby Ruth’s in the candy machine were stale.  

If you're talking about Sheriff Sale you will need to go to the County Clerk and see where they handle the auctions.

People can't dedicate time to building wealth.

I would like to build a team in OKC.

In one day I drove between three counties to show properties to clients.

But the deed is signed and filed in early 2024 after the redemption period and after the county gets it all together.When would the IRS consider the sale final?

Something that is a new build or recently fully remodeled you can get by with a lower number.
