Needing Rental Guidance Before Contract / Section 8 - Newbie

Hello! I’m familiar with the 70% discount for my investors here in Columbus for rehabs and I’m always working on getting my offers as low as possible. However in a situation where the house may go for a rental rather than a rehab and only needs a few repairs what discount are investors expecting on rentals? Example; this house I’m looking at she has section 8 tenants for the next year at $1250 a month guaranteed and she wants me to buy it for $92,500 (have not negotiated this at all yet). The location and ARV are nothing special most houses aren’t updated & are selling around $100k-115k. I’m Just seeing how I would work this out and any future situations I find like this. I’m happy to listen to a podcast if anyone can recommend. My second question is what would the best way to find rental buyers specifically those that work with section 8... I’m guessing through the section 8 website and then search landlords? Again just a new marker for me but I’m excited. Thanks.
