Very common in old house markets. 

There is no shortage of REI meetups, just make sure you don't get tricked into listening to a sales pitch (which is common, do your research).  

But that seems to be a fairly common ploy among scammers to convince you they're legit. 

@Benjamin Branson - this is a common issue in South Florida.

In my area old houses are very common and just the standard investment.

Your time figuring out how to do it yourself + cost of the software + risk of overpaying taxes due to your error + risk of overpaying taxes due to not using a more advanced opportunity + risk of underpaying and ending up on Uncle Sam's naughty list.

If so, it should be fairly easy to pinpoint which costs increased and determine if the increases are reasonable.One common way for closing costs to increase is if the closing date changes.

If I was the seller and gave you access to all the common areas where things like galvanized piping, tuck pointing, and lentels could have been seen during that walk through.If there was limited or no access provided prior to offer being made, that is another scenario. 

Part of the scope of work mentions receiving data from the common platforms so they can verify host compliance.

Seems like a common thread from a number of investors that post on BP about how they lost their shirt buying a property based on photos.
