If it is rain water penetrating through the roof and making its way to the interior space the sheetrock, insulation and framing may need replacing as well.

I would the make the worst case assumptions on the interior and add the two cost to figure a potential renovation cost.

If it's just a matter of removing debris and then an interior remodel, offer on it just as you would any other fixer and just include the extra costs in your rehab budget.On the other hand, if it's a really bad hoarder house, like this one:http://www.biggerpockets.com/forums/223/topics/133...You'd want to offer something closer to land value.

I'll be starting a first flip very soon, but I seem to be lost at the moment when it comes to finding the right appliances, materials for the interior (i.e., flooring, crown molding, etc.), if needed, which A/C unit to buy, and basically everything else.

Be sure to also make an offer contingent upon your satisfaction of an interior inspection of all units, pest and dry rot, roof, financing and so forth.

We cleaned and painted the entire interior, took all of the floor trim off, had the carpet professionally cleaned then reinstalled the trim.

My tenant has been complaining of an occasional knocking sound coming from the upper half of an interior wall. 

Hi Mike, Sam,I own 5 properties in Pueblo and several of the units are in much need of interior refurbishment -- specifically kitchen and bathroom re-models.  

I see this as a problem as one like myself can not give proper damage information to an interested investor if neither of us have access or have seen the interior of the property.
