Supply and demand as well as the legality.

In discovery they would most likely find the information even on a side note from documents you or the closing company could be compelled to supply.

The downside is office unIt can sit vacant for an undefined amount of time, maybe years, whereas multi-family is pretty easily replaceable assuming proper supply/demand.

things to look for:Current rental demandCurrent rental supply - are they building more apt complexes/affordable housing? 

I'm working with a few people on multifamily... right now people are asking a bit too much... demand has dropped off a bit but supply hasnt yet taken the hint.

The supply and return plenums will likely need to be re-worked however if you can use the supply branches to the actual spaces, you could conceivably save a ton of money there. 

It is softening now but is still a seller's market with demand greatly exceeding supply in both rentals and single family.

My houses can rent for $150 more per month in June versus December, just due to supply and demand.

We cut the grass and found the house open in a few places so we went in and found building supplies etc but obviously no recent activity.

That's not a ton, compared to CA and NV and NY and FL, but it also doesn't lose much, if any, when things go south.Also we really don't have a ton of supply around here, as the big building uptick has been only fraction of what they used to be.
