@Alex Nameishi Conventional loans will require simple deferred maintenance to be cured prior to closing (chipped paint, wood rot, broken windows, etc). 

How much is needed to cure the default?

Serve the appropriate "cure or quit" notice for any other violations of the rental agreement.

The paint will cure and apprear okay if temperatures drop further, but it can stop coalescing.

There are a number of ways title can be passed and defects or deficiencies can be cured.

An ounce of prevention and planning is worth two megatons of cure if things go bad....and they will eventually unless things are well-documented.

Refer them to your"no pet policy " . give them a cure or quit notice .    

Verify the assignment and allonge (not recorded) chains and have the Seller cure any breaks.If the loan has started foreclosure, you will want to review the foreclosure documents.Servicing information will come from who ever is servicing the loan.

Typically residential inspectors won't give a cost to cure - it's not what they're paid for and I've found they're uncomfortable even giving a ballpark estimate.

Upgrades and updated finishes, as well as curing functional issues that were created by 70s builders such as doors into bathrooms through closets, no actual master shower, no doors to master bathroom.
