Little details like that are why I obsess over digging deeper than just the metrics.Metrics I find useful:Expense Ratio: Look at operating expenses as a percentage of gross income.

I have to decide if im going to use a new injection of capital from the sale of my primary residence to:1) Hold in treasury bills at 4.5 percent until I find another property to purchase2) Pay off one of two existing mortgages, one at 3.75 percent and another at 4.5 percent3) Just find something to buy that beats either of those percentages on paper and be done with it4) Possibly loan out some hard money/broker it to a friend to allocateIts never an easy decision, but its a good problem to have.

These are really questions for your attorney - the more typical scenario for a jv like this is you have a new LLC where you are the manager of the LLC and the investor also owns a percentage of it.that way you don't have to deal with transferring it etc. 

This will allow you separate business income and expenses from personal income and expenses.Since you plan to house hack your bookkeeping and tax return preparation will be more complicated because a percentage of your home expenses will be personal deductions and some will be business deductions.

A very small percentage do it an easier/softer way.

Rene,To me it really depends on the market you are in. what percentage of the rent and monthly expenses does $100 represent? 

However, there will be a segment with a high percentage of reliable people.

As you build your net worth, you get more granular control of the percentage of it that you can put into any one investment.
