Probate, 60k equity, first time home buyer, tax mitigation

[Blaid Butler]

Hi everyone,

First time posting and am new to this world. 

I have an opportunity to buy my grandmas property at 341k and is valued at ~400k. We will have to go through probate to become administrator. My questions is, as a first time home buyer, what would be the best way to acquire this property? would an FHA loan give me any additional incentives as a first time home buyer rather than a normal mortgage? Is there a way I can keep her property tax rate or will that be reevaluated when I acquire it?

Thanks in advance!
