Recent sale of the assessed property is de facto value.Expert is needed for anything else.They can raise the value if you appeal.Comparable sales only count if they were closed before the lien date which is one year prior to the tax bill date.

Everytime you get close to depreciation running out (or want more) you 1031, expand your holdings, and your tax write off. 

Quote from @Alexandra Feig: Hi all,About to close on a property in Columbus and seeking some contractor recommendations!   

Start by talking to a cross-border CPA and attorney to handle taxes and legal structures properly.

Double check your lease, all the legalities and still check with the landlord....

@Dave McIntyre were you able to / are you ever able to get access to the property after winning the bid but before closing (assuming it's  a vacant property)?

Someone mentioned wanting to be within driving distance of a property, but I actually prefer not to be close.

Contact a local closing attorney as they may have one for you to use. 

The bank I work at would require the property to be close by.

It appraised for $201,000 and I put $103,000 in my pocket after closing costs and previous mortgage payoff.
