In my area (near the beach) its mostly families and they want cabanas, baby items, chairs, coolers etc that we do not provide but I have a local vendor that delivers and picks up these items and charges a few dollars per day for each item, and give me a 20% referral. 

I don't know your area, so I can only write to my experiences in PA.You don't really convert your property to Section 8 (S8), but rather sign a lease with a tenant who happens to be funded by S8.

In theory, you could QT the property to an LLC in your name and enter into a lease with you personally.

That's it, but a) print out a page for each property you think is comparable, b) make the list of repairs long and inclusive of everything you've done. c) Put larger items first like kitchen remodel......and don't just say 'kitchen remodel', list things like 'custom backsplash tile/Bosch appliances/recessed can lighting/pot filler/etc. d) Cite the price/value of the work done, and don't be afraid to be generous.

Are the units bought or leased?

On the other hand, if you write something into the lease that you agree upon, it should be fine, but that may turn off many prospects IMO.

That didn't help so now I'm looking to charge the late fee and interest as allowed by my lease.

They’re requesting what feels like an unreasonable amount of information, and the demands keep escalating.So far, they’ve asked for:A video tour of my home officeCredit checks on me and my partnerCopies of the deeds for every property we ownA copy of my partner’s home lease and utility billsBusiness phone billsA signed letter from the bank verifying our accountsBank statementsHonestly, it feels more like qualifying for a loan than trying to become a customer.

We’re looking to renew lease until June 2026 would like to move in new house.

You might choose not to renew leases, make improvements, and then raise rents after taking over.
