I've got a rental that was a new construction in 2022, so no property tax was defined yet (based only on land value.

Wondering if it's necessary to have a professional to the accounting work as to not mess it up for tax reasons.

There are only three instances where it makes sense to buy solar panels for your house.1 - You are living off grid. 2 - You live in a state that has sky high electric costs AND great tax insensitive.3 - You have lots of money, don't care if you are paying more, and want to feel like you are saving the planet (even though you really are not). 

Also any advice on how to lower the tax on my flips. 

I was thinking of paying a mentor to help but I don’t know who I can trust or what their fees would be to help . 

NY laws also require permit filing and permit fees.

I am using a CPA to do my taxes. 

DTIs do not apply, not tax return / personal income eval

-I am quoted a higher interest rate and more fees since its a rehab loan. 

This means that you will probably need to pay registration and filing fees in at least 2 states if you don’t buy CA property as a CA resident.Be sure to tell your accountant that you may now need to file non-resident income tax returns in each state where you own property as well.
