If so, what type of experience have you had ... positive and negative? 

I really want to try to just let that one lie though due to the family thing, it is already ugly enough.At least I feel like we are well known in the community for positive behaviors. lol  We were an EMT and a Dispatcher there. 

The biggest concern I have is that most individuals in my network will not be able to cover the whole $100K purchase......and I wonder about having 3-4-5 private loans and the costs/hassles associated with that.  4th lien position? 

Normally you want their income to be 3x the rent (1000 rent = 3000 per month salary). 

Sometimes I find it hard looking at all these properties and having positive cash flow using either the 2% or 50% rule

However, your lender will retain first lien position, and you'll take the second lien.Note that most mortgages have a "due on sale" clause which gives the lender the right to call the note in the event the property is sold.

Or you can easily remove with new appraisal because of equity position but that will add closing cost and you will be able to cash out some money also.

Yes you'll use leverage to make up the debt difference but this time your back is covered with the bed rock of the cash properties.the quicker you can get your husband comfortable with your financial position the quicker he'll be out there hustling flips with you full time.  

The goal for me is to use the rental income to pay off the debt so I own the property free and clear and pocket the positive cash flow.

I am also interested in investing in DFW and have been working with a realtor to find a rental property generating positive cashflow.
