In Massachusetts it's illegal to refuse Section 8, however, as someone who has been renting to both market and Seciton 8 tenants since 2016, I have very negative experience with Section 8. On average they're definitely NOT as qualified as market tenants. The author, and those who haven't dealt with Section 8, are naive for thinking that they are. Here is my experience with Section 8 in MA:
1. They see the lease terms as "suggestions" rather than "rules", often getting illegal pets, paying rent late (sometimes not paying it at all or playing stupid claiming that they thought Section 8 already paid for them). They will damage your walls/doors by slamming them when they get in fights with each other and claim it was "like that to begin with".
2. They expect to be pampered. They know the laws, they know how to play victim and will often play that card against you when convenient for them. I had a lady who would routinely get in fights with her boyfriend, and after he or she would damage doors by kicking them they'd expect me to fix it for free. When confronted, she would call inspections department to complain.
3. They don't value your property (see bullet above) and will damage it. Moreover, their damage will often exceed the security deposit (if you can collect it from them at all). There are also agencies that will pay security deposit for them (so they have no skin in the game).
4. There is a lot of drama. If they don't get along with their neighbors (or neighbors confront them about noise or disorderly conduct), they will text you with a frivolous accusation about the tenant in question. Similarly, if you don't side with them, they will escalate with a frivolous accusation to the housing authority. The housing authority will typically side with the tenant because that's how their rules are written and those bureaucrats do't care about you. In their eyes you're guilty until proven innocent.
5. Housing authority often does not respect you or your property rights. They will force their own lease on you, completely ignoring yours. Their lease protects themselves, not you. This practice may be unique to MA (and in my opinion should be illegal).
6. They're treated as a protected class by courts. Evicting them is a nightmare and can take years. That's a years of stress, reduced rents (because you'll only be collecting rent from housing authority), tenant retaliation (damage, running your water 24/7, frivolous inspection calls, they get very creative when they have so much free time due to being unemployed, as is often the case). One tenant I evicted ran up $20,000 water bill. Would you want a tenant like that?
7. Similar to previous bullet, they get a free attorney in court (at least in Massachusetts). You do not. That means they're interested in dragging out that case for as long as possible, meanwhile you're trying to get them out before it costs you tens of thousands.
8. They are extremely good at playing the victim card. They will bring their entire family to court, as well as a mandatory crying baby that's not even theirs to get the judge to sympathize with them. Even if you win in court, the judge will often ask you to make multiple concessions, such as giving them extra time to find new housing ans/or paying the security deposit + first month rent for them for the new landlord (so that the cycle continues).
9. The courts are extremely inefficient, and they have no motivation to improve because it costs YOU money, not them. Courts will stall the case for months (and this is pre-COVID) encouraging you to "settle" with the tenant instead of going through with the eviction. This is basically government-facilitated extortion, where you'll pay several thousand dollars to get the tenant to leave so they're not holding your property hostage.
Not all Section 8 tenants are like this, but majority are, avoiding Section 8 is one of the easiest ways to minimize landlord headaches and expenses. And this won't change until the government stops being blind to these issues.
