What evidence do i have to support he has to pay the last 15 days?

I'm concerned about what tech support we might need to provide, what issues others have faced, and if this service would be a differentiating factor for tenants. 

Don't forget the BRRRR and rental cash-flow if the market supports it. 

For the time being, independent mortgage brokers have a pretty staggering advantage for 2nd homes and rental properties, just by virtue of the wholesale mortgage channel having far more market efficiency.

Minimal support throughout the process but you get what you pay for.

I tried requesting the sales agent to help with the situation but get the feeling that neither the request has been considered nor represented for potential management support.

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. 

The tenant who’s staying until April just asked if she could bring in a support dog.

Look around my blog, youtube channel and (recently) tik tok for a bunch of good guidance (search for richonmoney).
