Why would someone-in this case a husband/grantor have a warranty deed drawn to grantee and in this case being himself again and his wife together. Also the city records show the purchase price way under the property value. This warranty deed says 25k and 4 years earlier sale was 79k?

It sounds like the husband wanted to add his wife onto the deed. So he has a deed prepared where he is the grantor/seller and he sells the property to himself and his wife, as grantees/buyers. The amount of the sale may have been listed as less in order to avoid paying taxes or recording fees.
