On this one we'll use 600 sq ft as a base for multifamily, and 1000 sq ft for a 2/1 SFR.4) How much do you pay per door for rekeys?

I also wonder how they got into the home if you have the only keys, or did they get a locksmith to "re-key" the locks?

You may not have a list of go-to locksmiths, handypersons (I don't know if handymen is sexist in 2017), cleaners, etc.

You can't worry that they pay a locksmith vs. a handyman.

You can buy a re-keyable lock (eg kwikset) and install it now and change the key when she moves out. 

Have a locksmith go with you, tenants probably changed the locks on you.

They've said that they don't keep the keys anymore since the mortgage lender called them to terminate the contract for the house right after the approval of the sale by the judge.I do have the following question:1) Is it legal to call a locksmith and to change the locks of the house and thus to enter the house?

If the seller/tenant doesn't leave the keys, we'll just open the door and switch out all the locks (which we always do anyways- The Mr is also a locksmith).We do see progress on the seller/tenant's move out, so that's promising.

The property manager should have a handyman that could take care of oddball jobs (rekey, broken doors, lightbulbs, etc) for bigger stuff like HVAC, plumbing, electrical, it's almost worth it to just call one of the big names and have them come out and deal with it.

Do you generally have to get a locksmith to make you keys to the house?
