Perhaps a nice 1950's built bungalow.Always hire a 3rd party property inspector to give you an unbiased feel for the home.

We are living in the main front house and renting out the ADU to a tenant.My question is, other than having landlord insurance on the ADU, a solid lease agreement, and a 3rd party management company as intermediary to help manage repair needs/requests (my partner and I both work full time jobs) and showings when the unit is vacant, is there any legal entity protection or other avenue that will protect us further in case of a tenant lawsuit? 

County and school tax info can be viewed within most real estate listings however its always smart to call the collecting party and verify accuracy.

If you don't have something structured where you can keep everyone is a seat for 30 to 45 minutes then you may as well just smoke some joints, drink beer and whiskey and have a wild party nobody will forget.One meeting could be for flipping, single family investing, multi-family investing, the best ways to find properties, how to do rehabbing, how to deal with contractors, how to do the math for single family and multi-family investing before and after the purchase, financing, dealing with commercial investments, how to do accounting and reduce taxes, how to streamline your entire operation, what software to use and how to use it and a lot more.Most meetings have only coffee, water and cookies for people to munch on and not much more.

They will increase the value based on what you did.Your risk with the tenants part is --where the property is would one big house be worth more or a duplex? 

If you hire a third party, you have a receipt proving the carpet was cleaned.

They hire third party service providers with low negotiated prices.

who's this 3rd party trustee that's going to be managing my money?

Best part is you ask a question in the forums, and get some priceless wisdom from much more experienced investors. 

This deal should have a title co/lawyer involved to make sure both parties are best protected and they will have one or a lead on one.
