Circumstances like not holding annual meetings for corporations, not having corporate resolutions , commingling funds, taking money out of the corporation personally without that withdrawal being either a salary or dividend, etc.  

Have them sign a holding agreement and pay over the deposit. 

I believe anyone starting (buy and hold) should start with a multi (2+).

For example, if your old tenant moved out November 25th and you place a new tenant 15 days later, then you can hold the old tenant responsible for 15 days of unpaid rent.4.

If the plan is to hold for 5 years and sell then maybe existing is ok. 

Are they holding the money, or are they spending it?

If you are working with a reputable company, then you buy the property, hold the property and look up 7-10 years down the road and have a home that has increased in value and a debt that has been reduced by your renter.   

There is less competition now and the saying "Don't wait to buy real estate, buy real estate and wait" ALWAYS holds true!

You hold it long enough or pay it off faster, now you got a property for low initial investment with a chance of cash flowing a nice amount when I get older.

If you’re a California resident, the state will still expect you to pay its annual franchise tax for your LLC, even if the LLC holds properties out of state.
