@Wei Jie Yang, where are you looking to rehab and what type of property, deal size, etc.? 

The charts below show the Raleigh area MSA (Metropolitan Statistical Area) general home price index over different time frames.

How big is each unit.. are they efficiency apartments at 350sf, or more full size at closer to 1000sf?  

Perhaps not a bubble...but prices do seem too high for a city and economic base of this size.

The closer the better, the more similar in age, size, use and condition the better, the more recent the better. 

Around here (Kansas City), I would expect some $89K houses to have washer and dryer hookups, but not the actual appliances; the other houses at that price might not even have the hookups.If the laundry area is sized such that only a stacked washer and dryer will fit, that might lean a little bit towards you supplying them, because most people probably don't have stackables already, and they are more expensive than the regular ones. 

We have 9 SFR and 1 commercial property at this time to give you an idea of our size and use. 

Although the property value is not on a fast track upward, it is a desirable property due to its seclusiveness and size (3500+ sqft).
