Since you have occupied your unit for two years, half (assuming both sides of the duplex are identical) of your gain would be tax-free (up to the $500k limit for married couples filing jointly) under Section 121.

For a conventional loan, banks have pretty close to identical terms since it's not our money but Fannie and Freddie money. 

Was it a case of a fake identity?

Actually I meant I have paid $80,000+ MORE than neighbor with identical unit.

For additional protection I make an effort to mask our personal identity as well as possible through publically filed records.

What kind of identity protection does everyone else use and why?

I assume I'd be jumping through identical hoops in that case?

The new evaporator coils are identical for R410A and R22 EXCEPT for the size of the flow orifice (or expansion valve, if this is used instead) and a higher pressure rating to accommodate R410A.
