I represent a remediation product called Penta-900 that has a highly respected reputation and a large number of proven clinical tests but even if tou find the right testing and remediation companies it may not help.  

@Lou R.There are many possible reasons:NOI numbers in the pro forma are likely rosy ... a thorough analysis could tell a quite different story;There may be other liens or defects in title on the property;The building is facing functional obsolescence or is carrying too much deferred maintenance;There is a forthcoming change in the local economy (major employer downsizing/leaving) or neighbourhood (redevelopment, highway or manufacturing being built close-by);The list goes on, but it always comes down to a lack of value in the proposition: either there is a significant problem with the business or the asset which makes the acquisition costs unreasonable.Now, sometimes this can be a good thing - if you are certain you have identified the issue(s) and know you can effective remedy them at a cost which the business could afford, you may have yourself a deal.  

It may not be difficult to remedy but will come at a cost.

Any remedy yet?

If a tenant asks to do something, you say no and they do it anyway is there a remedy for the landlord?

The only thing I'd caution you on is some of the homes built in around 2000-2002 were constructed with Chinese drywall, which can be very costly to remediate and is a major black eye on a home.

From another site on Home Buyer's Remedies, "If you have been financially damaged by the seller's breach of the purchase contract, suing for money damages may be an option.How much can you ask for?

My reading of PA case law (I'm a lawyer but not in PA)  seems to say that if the bureau fails to provide notice, the remedy for the mortgagee / lien holder is that the purchaser takes the property subject to the mortgage / lien and not that the judicial sale is invalidated.

I'd schedule a walk thru of apartments do like 15 to 20 a day along with maintenance guy. take notes and have a sheet for every unit that is like a check sheet kit, bath, windows, floor, so you can check anything that needs fixing or if you need tenant to clean make a note and tell them unsatisfactory condition you have 7 days to remedy and I will recheck.

If, for example, you were to renege after payment, the buyer would have to come after you to rightfully gain their property, but they would have plenty of remedy from a simple civil suit all the way up to possible fraud charges (i.e., it is against the law to sell something, collect the funds and then refuse to surrender the item).
