It's not unusual to find 2x4 rafters or 40 amp service above the kitchen sink etc. 

Would it make sense to have my property management company manage the renovation on any new property acquisition or find contractors myself to do the reno? 

I have been recommended to find the best team in market- REA, Contractor, etc.

I plan to invest in nj where house appreciates well. how to do I find the true appreciation rate for certain towns ?

How did you find this deal and how did you negotiate it?

I have always preferred to use an agent to rent out my BK units, as I find renters that are paying the fee are more likely to stay for longer durations, and be better qualified tenants.

Since being an agent I have learned so much about investing, found local mentors, as well as finding BP! 

I will try to find out.

Make sure you find a good property manager unless you are prepared for a part time job and being on call to keep the operation going.

-where is the best place to find deals online?
