I see most people that have 10 or more units almost always use an LLC but it seems to vary widely when someone has 5 or less units.

The state of MN leaves it wide open for renters to take advantage of landlords. 

I want to buy a Double wide mobile Home sitting on an acre.

Manufactured home is a single wide with a full length addition and a 400 Sq Ft covered porch.

This may be too wide a question, but just wondering: for those who purchase SFH's in stable, linear markets, what would be the average annual expenses you see on a long term buy and hold property. 

I have a wide variety of interests, financial freedom and exotic cars being a few towards the top of this list.

Hi All,How much do you guys usually approximately pay for labor (not counting the material) to do a full interior remodel of a single wide 14x70 three bedroom mobile home?

This will also widely depend on your PM.

Would she be interested in learning from a different angle, such as becoming a real estate agent?

Unless you can find a team that to join that will pay you while you learn, keeping your full time job while learning the practice on your own is probably the most widely used technique for making the transition.
