Are you only allowed to work for your employer/sponsor?

The people living here are a nice family, with a large dog, that I allowed them to keep with certain rules.

There should be a clause in your lease that allow you access to the home within a certain amount of notification time.

I open my calendar 30 days out as well to allow for future reservations.

Typically, a cost segregation study identifies and reclassifies certain assets to shorter depreciation periods, allowing for accelerated depreciation deductions and increased tax savings.As a rough estimate, the tax savings from a cost segregation study can range from 15% to 30% of the reclassified property value.

You just may need to install an interior door that doesn't allow the upper tenant to access the lower unit.

AND when you are ready to move in, take down the wall and make it into your original house, OR BETTER YET, when you are ready to sell, sell it and it will likely command more money than your 5/3.This will allow you to keep the house until to can settle your feeling and make a decision on what you want to do.

Also, we explored the option to do a boundary-line adjustment and compensate the neighbor for it, but he has a grandfathered clause in that allows him to build on the lot without meeting the new city requirements.

Hint: look for a solar architect, who acts as an adviser and works for you and audits the installer project proposal.Many states/utilities are no longer allowing net metering (kWh for kWh) and use instead all kinds of payback schemes (e.g. if you over-produce, they will gladly take your kWh for 3 cents and graciously allow you to take it back at night for 22cents - end result being, if your system is not properly sized, you will be producing energy for the utility and never recover the costs of the installation).

Contrast this with if you bought a turnkey/move in ready for $200,000, you can't add value usually (maybe update the kitchen 10 years later, add an ADU in the backyard if local laws allow that).
