If their financing fell through for some reason, would we just be back to square one except for me being a few thousand dollars richer for the assignment?

Join the thousands of other successful business men/women who are fleeing the state in droves, maybe?

Again, this isn't advice, but my experience (and the experience of thousands of other Self Storage Investors.)   

We ended up paying off the tenant several thousand dollars to make it go away, so proceed with caution!

Without a doubt insulate on your dime, a tenant is a person who has zero vested interest in weather or not your pipes freeze (unless their belongings get ruined from water). 

Although, we have spent thousands we still lIve our lives like nothing is going on.  

This will mean your overall numbers will be:     a - Income from Cash Flow = $6,000     b - Income from Option Consideration = $3,000     c - TOTAL income = $9,000     d - Cost to buy = $10,000     e - CAPEX = $10,000     f - TOTAL Cost = $20,000     g - NET Profit/Loss = (-$11,000)3 - After 5 years, your tenant/buyer doesn't qualify, and you are $11,000 in the whole on a house that you don't want to hold long term.So, now that I've ruined your night (or not), here is what I would do if this was my house.  

They won't tell you that, but it's true.In my experience, new wholesalers tend to focus on building a buyers list because they want to avoid the hard work -- finding deals.I don't mean to burst your bubble, but after years of seeing thousands of people come through these forums, you start to notice trends. 

They may be estimating 3 thousand for these and you could still contract them separately but you would need to see what they include in property management. 12% plus first month seems high. 

Our apartment building is right on a main artery that has tens of thousands of cars a day go by it.
