You need to check your state laws, but it sounds like you've done the right thing so far by giving notice, attempting to communicate, documenting the condition left, etc.The tenant is unlikely to sue you for anything.

There were tenants in place that the seller was prioritizing, which was why my lower offer came out on top since I indicated that I was interested in keeping any tenants conditional on rent roll.

I don't know your market, but I find that people will find ways to live within their means (e.g. move in with friends and family, etc.) than accept the market conditions since they can't afford it.Good luck.

It had a HUGE lot, the building was in excellent condition!

What condition was it in?

If the condition of the property warrants it, raise the rent to market rates once the existing leases are up.

DIY you can write out all the terms and conditions on a yellow pad and both sign it.

The cost is going to be less than 30k because I will build it myself but obviously the county won't just accept my "random" estimate, they will allow to estimate $123/SF of conditioned space and $22/SF of deck.The floor plan I was planning on building is coming at $37,404 (288 SF floor plan, 90 SF front deck), so my question is : shall I make it smaller to get below that 30k limit ?

Minimum standards include, but are not necessarily limited to, the following items:The unit must be kept in condition such that one person is able to clean within four hours.

If it is the former, pull comps and look at the condition of the home to back up your lower offer.
