@Darius Ogloza is correct in this is an item you should have known prior to sale.$1300 sewer bill sounds like a past due bill from the previous owner, though?

After i've done some research looking at the population growth, job diversity, unemployment rate, etc...

@Chad Coleman as others mentioned, it's probably one or several of these factors: priced too high, isn't marketed correctly, doesn't have the right combination of amenities for its area, this is the worst time of year to list, and this is the worst year to list since the recession ...it could be one of those items, all of those items, or a combination...A suggestion:In most markets, price reductions have increased exponentially...however, I constantly see sellers making small, almost meaningless price reductions of 1-2%.

If you later demo the property, you do not recapture bonus depreciation on these items.

If I get a HEL on an investment property to build a primary residence, is the interest on that loan considered interest on a residence that can be deducted with itemization?

And, it will be a forever process; real estate is so diverse and always changing that if anyone tells you that know everything about real estate, you should thank them for the warning and bolt!

We do two of the items on your poll.We offer MoveIn Specials - best one is a free month of rent. 50% is credited for 2nd month, so they can't use it to lower MoveIn cost.

I used to buy nice kitchen items until they kept disappearing.   

.; foundation/structural settling, improper water diversion systems creating rot, etc. 

(most people are unsure of how to record the items from the closing)2) improperly recording payments made to and from a property management company3) Improperly recording payments made to mortgage companies(not allocating it between interest, principal paydown, escrow)
