@Hamidou Keita you ant to be careful in selecting an agent and a PMC!

Exercise great caution when selecting contractors, as there is no Planning and Zoning (P&Z) oversight in this area, which can lead to build issues.

There would have likely been a public notice of some sort as well if a major change was going to be made.

I’d love to hear who you’ve used in similar situations, or what sort of rates and terms could be expected.

Find local RE groups and join them all till you sort down to one or 2 local RE groups.   

I am undecided if I should repair it and rent it out or should I  repair and sell it ( fix and flip) sort of.

What you are describing is called adverse selection - you have a known issue and want to buy an insurance policy to fix your problem because that is less than what it would cost to have the work done and you pay directly to the trades. 

If your goal is assume a loan, I would offer the lender some sort of compensation as they are generally only paid if they write your loan, which is not the case with an assumable loan, as the current servicer will be underwriting and providing the new loan.  

To avoid going through the same poor experience, keep reading.Even if someone gives you a referral here, do NOT make the mistake of assuming that the PMC will meet your expectations, just because they met the expectations of the referral source.In our experience, the #1 mistake owners make when selecting a Property Management Company (PMC) is ASSUMING instead of CONFIRMING.It's often a case of not doing enough research, as they don't know what they don't know!

Often times this is a "ask for forgiveness than permission" sort of scenario.
