The best recommendations that I can give you are to really know your market well and also to be very selective on the deals that you do get involved with, meaning that you'll likely reject a substantial amount of deals that you look at. 

You have select volatility when it comes to micro housing bubbles, but for the most part, real estate prices are relatively stable.I have owned and operated a number of rentals for decade.

If they want to provide a discount for all items selected, that is fine. 

I still broker loans on a select basis.

Have your lender select the 203k Consultant to get the info up front at the beginning of the process instead of waiting until close to the end of the process by waiting on the appraiser. 

Can anyone recommend an awesome real estate agent or two to help me see properties I've pre-selected?

Select “Application for Certificate of Occupancy”, and fill out the required information in the application page.

My biggest recommendation to everyone here is to vet your subs as much as possible and above all else, don't select based on price.

Most of the violence in Allentown is within select groups of people.
