The loan options and underwriting will differ depending on which path you choose.

Days on market are around 70 days on average, depending on the area.

Will depend on several factors like the type of property, type of tenants, your risk tolerance, other assets you own, your estate planning, laws where the property is located, etc.

They need to do all their due diligence including understanding the value that will be added by the ADU, the finance options available, the consequences of adding the ADU (rent control, property taxes, rental limitations, etc), etc.Good luck As with all things, it depends on the investor and the equity.If they are able to leverage existing equity to buy it under a HEL or HELOC, then they are adding equity with no out of pocket expenses, and adding immediate and longterm cashflow to existing stock.We like ADU's because there isn't more land being created in our city that is landlocked...but there is more density available to those with large lot under-utilized sfh.In my market, it typically costs $2 to add less than $1 of value on single build ADUs.  

The rules for who may represent an LLC in a court depend on far more information than is present.

They can depend on the person and the property along with a multitude of other factors.

Really depends how you want to structure it. 

Also 3 brs will get anywhere from 1k- 1600 depending on where, YES they pay MORE than cash tenants.

I think it depends on the condition of the property whether it needs full replacement of most parts or just cleaning refreshing.

@Lucas SchlundI agree with @Ty Coutts that it depends on your risk tolerance and financial stability.
