Before you pay ANYTHING , demand  a cert of workmans comp from the company , a certificate of insurance , a business license , AND all the information for a 1099 . 

@Miriam De Haro  I always did my final walk through with clients on the way to closing for exactly this reason.If I was representing a buyer and came across a situation like this, I'd demand a holdback of funds sufficient to remedy the situation or I'd refuse to close.Too late for that now. 

Your PM will probably demand a lot more money which will make it untenable to use them.

But lowering interest rates can trigger increased demand as more people will be able to afford to enter the market; hence triggering house prices to resume going up.

Be cautious and demand a good deal (which are, admittedly, harder to find these days).

You might also ask your future property manager to analyze the furnished rental market and short term lease demand as well (6-12 month lease terms). 

Should we demand a discount on our mortgages since the lender is the one holding the note on "their" property? 

@Jay Maranan just an FYI, my primary property is 5 stories, of which almost all the carpet in the units has been removed(90%)...the original flooring is beautiful oak, that was original installed over 90 years ago, however, the units that just have the carpet torn up, sanded and stained the original flooring are much louder that the units, that I lay down subfloor, underlayment foam, and new floors over the original solid wood(I know it is sinful to purists, to not refinish the original wood, but it cost more, takes longer, is louder, and less isolation of bugs, and leaves some of the earthquake retrofit hardware exposed, if I do that) ....BUT, with carpet and/or wood floors it will be noisey...that's why the 5th floor are the "PentHouse" units, since no upstairs neighbors, even though identical layout to the below units, they can demand a bit of premium, especially if your new tenant has lived in apartments before.

If not, I think it would be reasonable to request/demand a refund. 

Now the market has totally shifted: high demand, a lot higher rents.
