This is a tenant that we procurred ourselves after buying the unit.My other thought about correcting the issue, as mentioned already, is to adjust the lease to make the rent due on the 15th.

I have spent a lot of money letting contractors supply materials only to find out they mark them up 20+% because they went and got them - you should do that yourself - there's a lot of education to be had in procuring materials.Lots of good content on youtube about MH remodeling - check out Drews Mobile Home Repair channel.
