I think your best bet is to have a call with a lawyer that handles evictions to come up with a game plan. Rules vary a lot from state to state and even by smaller segments. You might try and connect with people in this community to get referrals of the bulk eviction attorneys.... this is the difference between a 1k eviction and a 3/4k eviction...can you imagine how I know this?
I hear some advice about getting a property manager. I wouldn't jump on that yet. I have worked with a few and experienced rookie mistakes worse that what your describing at one of my homes by a company managing 600 properties. For a few hundred dollars (and a few passed tests) anyone can call themselves a property manager. The honest truth is that the great majority of them are not good.
I'd encourage you to review what sort of qualification requirements you want to require. I look a lot at applications like I'd be underwriting residents to buy a home. Additionally, self employed people get a lot more scrutiny as their information is difficult to verify and ability to collect on defaults is low.
If you go to a lot of large landlord or apartment complex websites, they will often list their requirements to qualify. If you can find a great leasing agent, it too can be one of the best things you can do. Like I said in my previous post, many leasing agents (not all of course) are total who res trying to get a fast leasing commission. In doing so, they set up the owners for a quick failure and massive turn expenses. Good ones can be a game changer tho.
As far as getting them out - I assume they are behind, but am not clear.
1. Try and talk them out, by indicating the costs and consequences of an eviction and how you can help them avoid it.
2. Hybrid / Cash for keys - pay them to leave. Start by offering to cover the cost of a moving truck for the day they will move out. Again, you don't put your own credit card down or guarantee the truck, you can go to the rental place and lay down cash so they may rent it. Sometimes that's enough. If not and you have to pay them to go, they get no money until the home is totally empty and you walk thru it to make sure they haven't blown it up.
3. Eviction
4. Grant programs. The government touts the amount of money available, yet has dispensed, from what I have seen less than 5-10% of it, which is about as ridiculous as the government itself. Additionally, the programs to get free money come with strings attached which I would never commit too. This, in my opinion, is largely a false hope.
