@Harvey Levin, you beat me to it! I'm a Section 8 landlord in St. Louis and yes, a lot of the info here is wrong (I'm assuming for IHA as well).
@Ryan Horan, I'm going to try to answer everything in your post and maybe even a few items you didn't ask for. Harvey, please correct me if I'm wrong specifically for IHA.
I recommend closing on properties with Section 8 tenants around the 2nd of the month if possible. This allows you to get most of the month's rents through the settlement and gives you plenty of time to get the new ownership paperwork in place with the HA.
There is a simple packet of paperwork to change ownership - I found it quickly here: https://indyhousing.org/housin...
You simply have to fill it out and send it in based on the instructions and the payments start coming to you. I submit this paperwork ASAP following the sale & request that all payments to the previous owner be stopped (here, by email) and follow up daily until I have been given confirmation that it's been processed.
You don't have to "apply" to become an S8 landlord. However, Indy may have some sort of class or something (the HA used to do that here but did away with it due to COVID).
If the payments do go to the previous landlord after the sale, immediately notify the HA. As long as you have done your part, they will make those payments back up (and require the previous owner to pay them back).
Each HA has their own rules around rent increases & timelines but they are typically not hard to get if you are under market and rents haven't been raised in a long time. Check with a local successful Section 8 landlord to get an idea of what you can expect there.
I don't love the $99 security deposit but for me, if the tenants are good and the rents can be raised, it wouldn't be worth kicking them out over. I might see about collecting more but I might not. Not sure on that one.
The initial lease has to be for 12 months. After that, it is up to you how long the lease is for and the HA will follow it. So you're in the drivers seat if it's month to month. You can give proper notice to have them leave, sign a long lease, etc. However, the HA evaluates the tenant annually (called the recertification) and that is at or around the time of the initial lease renewal. That date won't change no matter what happens with the lease.
You can collect rent from S8 as long as they tenants are living there and you haven't signed a notice to vacate and sent to the HA (required at the end of the lease). And you're following the S8 rules, which are typically easy to follow.
I have found that most landlords aren't very good with Section 8 so I don't expect a realtor to be :).
I'd recommend requesting the most recent Notice of Change (the document that lays out the amount of rent and how much the HA and tenant pays), which the landlord should have. It will also tell the recert dates. Then make sure that the ledgers you're getting match those amounts (it's easiest if the PM or landlord keeps a separate ledger for tenant and HA but a lot do not and it can take some detective work to decipher which payments are which).
Section 8 is a great program when executed well. A lot of landlords and PMs don't like it because it is some additional paperwork and it's very process oriented. I think the positives far outweigh the negatives. I have some blogs here on BP that may give you more insight if you're looking for more.
Good luck!
