@Brian Gibbons Nailed it.The one thing I would emphasize is...when you are selling with any kind of option or seller financing, always use a local & reputable RMLO. 

There is reputational risk in this type of activity.

I would suggest possibly JVing a deal with a reputable flipper in the area.

We fear any hint of foreclosure or bankruptcy, believing that either one would destroy our bookings and reputation. 

That's the kind of thing that will pay off in a good reputation that will keep our building full.Never forget that you are running a business and reputation matters.

I would rather take my time and learn the business opposed to rushing and tarnishing my reputation by marketing bad deals.

If you are strategic about this, each deal will add to your reputation and credibility making it more efficient for you to attract and enlist new investors.

Above all, find a trustworthy and reputable lender that is fast and efficient but more important wants to work with you and BUILD a relationship. 

As @Laura Guy and @Shawn Holsapple said, FS Houses is as reputable of a company as you will find to work with.

If you can't do it, hire someone, but before I spent more money finding out I didn't have a deal, I'd come to agreement on a price.Your agreement can be X dollars, less cost of repair of any single deficiency over $1,000 that will reduce the price to a bid by a reputable contractor agreeable to buyer and seller.
