Again the goal would be to provide them with an attractive package, while still allowing me to profit off the property and preserve as much of my capital as possible?

I would also suggest to go with what is called vinyl package: the jamb/extention and casing/trim is vinyl as well. 

Also,  how do you guys go about finding the best lender packages?  

Get them to take action fast once they receive your package.

(I would if they want that as part of their loan package, but I would do my own pro-forma and check the calculator, making adjustment to entries for their calculator to provide similar results, you should always put your own pencil to your financing requests. )Be conservative with income projections, debt coverage ratios are a minimum of 120/125% and may be higher by location, type of project, experience and asset coverage. 

We also give gift certificates/coupons to these businesses as part of our "move-in" package we give each tenant.

They have all taken the classes in our education package and some also have experience in C(r)ook County.

Still - they've been up there for a while, could pick all of them up and negotiate a package deal.

For our listings they typically paint and replace carpet, do some landscaping and will sometimes include a new appliance package.  

Meantime, find another lender for that parcel and start over (don't have the package "moved").
