This will give you the hands down most valuable skill in RE which is sourcing good deals.

But a good skilled worker, whether GC or sub's, can be invaluable.With all that said, to try and save money, I would see if you can find a good home inspector referral, many of them are or were GC's themselves, and pay them to check out important work that you have done.

To be honest (as a business owner myself) I have been surprised by the professionalism and communication skills of these lenders.

You have to turn on possibly a new skill of protecting your new found assets.
