I mean, yeah that's got sketch vibes, so I'd tread lightly because this is probably going to be the first but not the last red flag. I lived somewhere once where something seemed off when we signed and it was a nightmare of a year including when we tried to get our security deposit back. So I'd cautiously proceed-- all the LLs I mentioned were by the books and protected themselves, but this is way different. Also, this gives me "if I don't like you and your gf I will also do sketchy things to push you out" vibes since they've sort of given you that playbook. I'd go off of whatever vibes you get tomorrow, but when I lived in buildings run where they were outspoken about sketchy stuff like that they were usually pushing boundaries a lot (avoiding their taxes, not providing stuff on the lease, stiffing maintenance workers, not providing/deducting security deposit like legally required).

Also good it would be lower because 2600 that area is....high. I would avoid Rochambeau and Camp intersection possibly too (feel free to dm me as you proceed with this process). Also you should know that in RI they can't ask for last months rent too-- it's weird to me how many people move here from MA and buy and then ask for more than 2 months up front when it's illegal.

I saw one place asking for 3 months (first, sec, and last) and the owner seemed nice, but I later saw they listed and sold only a few months later. If I had fallen for that, I probably would have never seen that money again once it changed hands-- glad I went with my gut and picked a different place.
