My fiance uses this exact model on her retail store for employees.

It would be wise to have a very long option period so that as long as you are in a positive cash flow situation the model is sustainable.  

Thanks for setting this site up, I am confident it will be great to connect with like-minded individuals, learn from them, and offer my expertise in real estate construction.My wife and I are currently living in our 3rd "Investment" home, buying properties that were run down and fixing them up has become a passion of ours.

One of the guests talked about his venture into this model.

This agent will also advocate for your side and negotiate on your behalf with the seller and sellers agent, using all of her accumulated expertise to help you save money.

Brand new to BP and still formulating my business model but working on a strategy to specifically fill this niche and become an agent that can invest my agency income as a partner in investments. 

My mentor's model, Get Off Your Keister, & Get To Work!

My models are in the 70-80% ltv range for the primary loan.  80% of my properties are in Whittier and I havent ventured out of state so my perspective is biased.  

Note-all of the above was just my personal opinions, no expertise to back it up.

Notes by themselves, regardless of your particular business model are an awesome opportunity.
