Each option has its pros and cons, and I'm hoping to get some insights from this community to make a more informed decision.Option 1: Building an ADUPros:Increased Property Value: An ADU can significantly increase the value of my primary residence.Control and Proximity: I can closely manage and maintain the property since it's on my land.Potential for Higher Rent: ADUs in bay area can fetch a good rental price.Flexible Use: ADUs can serve multiple purposes – home office, guest house, or rental unit.No Additional Land Purchase: Utilizing existing property means no extra cost for land acquisition.Foundation improvements: I will get an upgrade for my foundation which increase house stability.

I've studied Rent Control, which is just a subtype of Nixonian Price Controls, and they are always a bad idea, they always produce the opposite of the intended outcome, with run down "slums" as they are unprofitable to maintain at submarket rents, If you read the whole letter, Biden actually has a better idea later down, which is a massive govt' push at fed and state level to increase production of new housing stock at all levels, using tax breaks, incentives to developers, thus eventually lowering rents or at least slowing rise to let incomes catch up.

Learning the basics of electrical , plumbing , AC , painting etc will help you in this line of business which also save you a lot when you acquire your first home.This is how I got started , maintaining the rentals of my uncle  when I was your age.

(Local cities to Auburn, AL) This is why I started to lean towards short term rentals, but I only started to scratch the surface on all the details behind operating and maintaining STR's.

Same with maintaining the home.

It will probably only get used during the winter. and I can see some maintenance issues too with all that moisture inside it would be easy to get mildew or mold growth started if it is not maintained properly and often. also it is traditional to follow up your time in the sauna with a dive into a nice cold lake (or pool), or at least you might want to have a cold outdoor shower nearby. personally I would spend my money on something like a hot tub before I bought a sauna.

Between all the licenses I already carry for my current business endeavors in different states, I'm not too keen on adding another set of licenses I would need to possibly study, apply for and take a test for then maintain with CE credits in an industry I'm not even sure I want to take on with any meaning volume.  

The types of coverage will change accordingly.Make sure every vendor who performs services on your property or on your behalf maintains appropriate contractual relationships whether it be directly with you as the owner or with an intermediary such as a General Contractor or Property Manager.
