When a tenant moves out, transfer the deposit back to Checking so it's ready to apply towards expenses or refund the Tenant.If you end up with excess funds in the Checking account, I recommend you transfer it to a third account designated explicitly for future investments.

If you want to be generous about it you could tell the tenants your operating costs are consistently going up (which is true), share the current comps with the tenant, and ask them what kind of increase they would be comfortable with.What are peoples’ thoughts on where rent’s should be set or the best way to get them up if you fall behind?

Does anyone have recommendations for ADU design and construction companies in San Diego county?

Do you like design?

There is a significant art to this, and that is why one won't find any standard template for doing such, because each original home style/design best lends itself to different layout potentials. 

The other half is: excellent finished product design and management at a reasonable cost. 

With an average of 92 days on the market for listed homes, we needed to craft a thoughtful design that would match the build of the home, and drive top dollar in the market with as few days active as possible Upon completion, this home received multiple offers in the first week of listing the property for sale and went under contract just 9 days after listing!

I think they would need to file the insurance claim if there was enough damage, but possibly they could escrow an amount you’re comfortable with if lender allows.
