I had to jump thru a few hoops to start a business in Bali, which allowed me to apply for an investor visa.

I have been running into issues with the neighbors at one of my long term rental properties. 

Is this a "find a different lender" type of issue, or are there laws about this? 

I have a property in Dayton Ohio, that i have been having issue with.

It is not unusual in some areas for radon to be an issue. 

How would getting traditional financing work from the banks being on a Treaty Investor Visa (E-2)? 

This normally would not be an issue but the cost of the water/sewer is extremely high in this area and specifically because the meter is a one inch, the costs are much higher than a normal 3/4 inch on a non-duplex. 

About 3 year ago had 1st floor washroom redone everything brand new recently have noticed in the garden washroom water stains ask about any water issue was tolled no so I went to look over the washroom theres crack grout between the tub and tile where water must of been sipping threw also water damage on the vanity doors and towel rack missing was tolled not installed correctly contact my handyman looked over the damages forward the price tenants says it's not there fault I was tolled to installed splash guards help prevent from water falling out the tub but since it was not  installed from the beginning it's not tenants fault they don't want to take responsibility 

It sounds like regular maintenance issues, some of which were tenant-caused. 

If in the county of San Diego or another city in the greater San Diego area, you still have an issue.
