I have the full property tax exemption in Texas for my VA disability, but I'm trying to get clarity on the property tax exemption.

I went on to say they are running an illegal offering, they never filed any exemption from the SEC and have you ran this by your attorney?

Having to buy another primary residence, to avoid tax on the gain of your current home, has not been a requirement for over 20 years.Assuming it was your primary residence from the beginning, and you have not moved out/rented it for more than 3 years, you gain is exempt up to $250k filing single and $500k married/filing jointly.

Strategically, I aim to fit into as many development exemptions as possible. 

Unless you have lived for 2 years in each unit, then you can only claim exemption on half of the gain.

How does federal tax exemptions or reductin for hurricane damages work?

If there are excess funds after paying the local/school real estate tax bill, the remainder can go to:Current real estate taxesCurrent Muncipal liens for water/sewer or any other bill initiated by the municipalityState Liens, usually for outstanding state taxes, sometimes employee/employer taxesPA State Inheritance Tax which applies to all deceased owners and starts at dollar one with no exemptions, unlike the Federal Estate Tax. 

In NC, SC, VA the entitlement process takes up to several years and potentially a lot of money for any implementation above 5 MW, which is why I favor the <500kW exemptions for "small scale" solar farms.

@Yixiong Pan  Pennsylvania State Inheritance Tax has no exemption and starts at the first dollar. 

Capital gains taxes if the property is sold, although there may be exemptions if it’s their primary residence.2.
