Jawsette, You've changed the definitions of well-defined terms and you've insisted that the evaluation of a rental be turned into some sort of twisted retail sale where you buy at retail and sell at a higher retail!

For a larger fee, you might insist, but not for $1KWholesaling runs on repeat business. 

---So, insist on them providing the rental application and supporting docs for your review.

When we do allow installs, we insist the wiring go through the crawl spaces, basements, and attics whenever possible.

If they insist ok but I don't offer.

I insist on a completed FREE application before showing.

Either receive it in check well before the move-in date so you can make sure it clears, or better yet, insist on a money order or electronic transfer.If you've never evicted before, go to clerk of courts office in the courthouse and ask for the eviction forms, and follow the instructions.
