As mentioned earlier in the thread by @Chris Seveney, real estate prices have been going up particularly in Northern New Jersey, so a lot of tax appeals are pointless or do not make any sense.

A close friend of mine in Houston once had a client who owned two properties across different states.With your North Port place being so fresh (2021 build) and on a canal, you’ve got strong appeal for folks looking to enjoy that waterfront Florida vibe.

Do those have any appeal for you, or do you like/prefer wholesaling?

Purchased on 2/1/2024 for $58,500, we invested $55,000 in renovations to enhance the property’s appeal.

So you didn't do anything wrong, you just didn't know.As for alternatives, most counties have an appeals process... but you will likely lose if you go that way.  

These properties appeal to students and low-income renters, especially if traditional housing is limited.

We are now appealing a denied claim with the insurance company.

This can be especially appealing for those who enjoy traveling or seeking occasional getaways.

The direct appeal is to lenders (primarily commercial lenders closing in the $5M-$100M territory).

Similarly, 73170 is in a growing area with good schools and strong community appeal, making it attractive for both renters and families looking to buy.
