I had a landlord file a claim on me one time over clean up that he gave permission to do - remove a broken-down screened in porch that was collapsed and a tore up rug in the living room.

Might be worth it to have a licensed plumber and electrician familiar with local code to take a loo for any glaring mistakes.On the plus side for getting it approved, in case something happens and you need to make an insurance claim, it's another out for them not to pay.I don't think use as a temp rental has much to do with permitting since you usually need the local municipality's permission since they're all setting quotas. 

Is it okay for me to just give out the information of sellers, or should I ask for permission first?

If you do fix them they love you and pretty much just gave you permission to raise their rent next renewal period.I hope this helps and good luck

We did, however, wait until we closed before signing lease & taking deposit... just in case financing or something fell through and we couldn't close.If it is vacant, most sellers probably aren't going to mind a bit if you ask permission to advertise and show it.  

Yes it'd be a short sale if the seller sold for less than what the house is worth and I believe they'd need the lender's permission to do so.

If you give your tenant permission and there is a city ordinance that makes it illegal, you will be the one that is held responsible. 

I have permission to take any means necessary but would like some guidance - so here I am.My current plan: Refinance the 12-unit using a combination of the municipality's offerings (i have many questions about this) and private debt for the rehabilitation of the building.

The reason they use a credit reporting agency is that they pull your credit data from the three bureaus, consolidate the all the info, get rid of duplicate info and put it together into an easy to read format for the mortgage lender.If these credit reporting agencies pulled your credit they should have had permissible purpose, meaning you applied for a mortgage with a lender and that lender uses one of those three credit reporting agencies.Now, the bureaus allow a 30 or 45 day window (depending on what score model the credit reporting agency is using) where they will group/or count all mortgage inquires as ONE inquiry during that time frame.

Could take about 3-6 months to get permission and schedule an inspection from the city.
