Hello,I've had some issues with excessive costs through my property management company over the years. 

https://www.singlekey.com/en-us/ - I believe they screen the tenant as part of their underwriting before issuing the rent guarantee policy and the tenant also pays the premiums. 

If the commercial space isn't too disruptive, you shouldn't have an issue renting an ADU up there.

No issues and tenants are renewing.That indicates tenants were paying below market rates.If the market rate for a 2-bed/1-bath apartment is $1,000 without utilities included, then he should adjust his rate to $1,100 because it includes $100 in utility cost.

We've used Reg D 506(b) for our syndications and ONLY communicate with investors that have a prior relationship with us.There are two illegal activities that I see all the time. 

I just set up my vrbo account and still some finer details about planning the communication, cleaning service, maintenance persons, etc…

They won't fix my issue nor respond.

Can anyone recommend good companies to root cause  and implement solution to fix this issue?

I do have additional coverage for the sewer since I knew it may have issues before I bought the property. 

It also allows you to manage paperwork and document communications with Tenants.
