Also if you don’t learn on to estimate cost yourself you will be taken advantage of by most Contractors I would suggest you take the time to learn “I know it’s not the easy way” and that way you will have a understanding of your real cost if you decide to rehab or self or hire a GC.  

I am wondering if something similar exists for a commercial property as well.All thoughts and suggestions welcome.Thanks,Piku

I suggest using zillow to find comps in the same neighborhood.

Research is one thing, but you have to have someone you can trust when something goes pear shaped at 2 am.Turn-key, as @Hallie Wasserman, suggested may be a good option, but those won't be value-add plays and returns are limited.

Anyone have any suggestions, success, or know of someone that does this for a fee? 

I have been researching creative financing to help with that any suggestions?

Thank you in advance for any suggestions you can provide!

No sorry it is not in my plans for the forseeable future.Alternately you could suggest you will have the work done by qualified contractors if he is prepared to pay for it.

I might suggest proposing returning half the deposit, which is substantially more than your obligation, just to try to get things back to smooth and friendly.

Thanks for the suggestions.
