My advice would be to look at Sacramento city proper, as well as West Sacramento and Citrus Heights.

As for STRs definitely check the rules in your area cause MA has a lot of restrictions on days.

They are zoning and land use regulations, accessibility, environmental factors, market analysis, topography and terrain, utilities and services, neighbourhood characteristics, restrictions and opportunities, development feasibility, financial analysis etcetera.

If the reason is particular to that lender, you can search for a lender that may not have the same restrictions. 

The attached images show the attic's current condition.The room in the back is insulated and and would require finished flooring, heat, & paint (62 sqft above 7 ft height). 

I have verified with USPS that each triplex address is in their database and that there are no issues with the location and height that I would install it at.

Lately, I’ve been encountering some challenges with municipalities imposing new rules and restrictions that impact my properties and operations.I’m interested in learning how others have successfully addressed these issues.

Has anyone written this type of restrictions into their lease?

Pinellas County has one of the most restrictive STR rules in Florida. 

Yes, I have a triplex in Cleveland Heights
