In short - if you aren't licensed to do the work -  your services aren't going to satisfy the permitting agency.  

It seems like not many accounts can be joint or if they are, there's monthly fees.

It's totally normal for it to take some time, often about a month or so.

If the tenant stays, they will be on a month-to-month lease, which requires a 30-day notice.

In 2020, it came to a near complete stop.Banks go through the foreclosure process typically taking 4-8 months.

There are companies such as Cover that offers a full service ADU deliverable from design through construction completion.

On my PM biz $2M of coverage is like $200 a month. 

After the inspection, we sent a request with a mortgage contingency date extension (because it was also difficult to schedule this with the agent), a credit for termite treatment and an extension for the closing date which would allow one of the current tenants to move out at the end of this month (when their lease is up) before closing.

This will give you a baseline of how much you spend per month.

Last month, I pulled the trigger on getting my first real estate property ever and decided to go with a 4 bed, 2 bath new construction to limit all the variables involved since I am still in college.
