Typically PMs pass this cost onto the prospective renter.

Always always ask prospects, customers, vendors, and subs for leads.

Prospective buyers look at the place.

Your most promising prospect will be from a sublease or a private party.

I am planning on investing into a real estate development LLC as a non managing member for the prospective development of a 90+ unit senior housing project.

Everything I have learned and know indicates that LLC are a better corporate structure from a tax prospective and for purposes of transferring property without any tax  penalties, but as an attorney that doesn't do tax work I recommend that my client's talk to their accountant.  

I do have my fingers crossed to have a decent reputation in six months, be more knowledgeable, and being able to utilize the marketplace and my colleagues to get stuff done, because if Gary Keller is right that you have to go through dozens or a hundred suspects to find prospects to find something worth getting under contract to get something good under contract, it would smart to have to let it go because I couldn't find funding/partnership.

For example: "Subject to 14 day inspection", or "Buyer shall receive key to the property and have the right to show to any prospective occupants."

You have to pay for it, but the list can be used mulltiple times for your campaigns.You can go into listsource's website and play around (free) by putting in parameters to get a count of prospects.

So that small incentive is the only one I'll do early in the lease term.Sometimes a prospect will come along and really want something simple.
