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.

OP Lincoln is a great town since it is the state capitol, lots of government income, home of UNL, lots of medical etc.  

You are one car breakdown or medical bill away from paying rent since you don't have an emergency savings.  

The trick is asking them what happened, usually it is for medical which I get. 

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.

My main concern on the outer islands is medical and infrastructure.

Whether the property manager charges to file the eviction (we do not) is a separate issue- a professional management company should file the eviction for you.Regarding the arrears rent, again, a professional manager should be letting you know that the renter has fallen behind and why (did they have a medical emergency? 

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. 

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.
