for those I used to have a wire type match holder about 2 foot long. 

Additionally, there were agent commissions that I would have had to pay on the initial sale between me and the bank, which in a normal wholesale gets passed on to the end buyer.

If it's pier & beam, then that perimeter footing (spread footing) should probably have been 6" - 12" deep.

Also, I will be self managing through my property management company, and wondered what a normal management fee for storage units would be?

I also carry a 1 million dollar umbrella policy on top of the normal "Fire Insurance" policy for each property.Even though I've been doing this over forty years, I encourage everyone to take a course from the expert in this field. 

Hi BP community I don't normally post which I plan to change, most of the time I'm just reading through forums.

However, I recommend that you don't touch this method with a 10 foot pole unless you are deeply experienced.

@John Arendsen  Exactly the portal owners generate their revenue basically exactly like any normal mortgage broker would..

You also save money on the commission you would normally pay an agent when making deals.

My exit strategy would be to bring the value up and then sell (assuming the comps are predicting greater value then my costs)  Preliminary research indicates that the cost per square foot may be significantly higher then i would be paying, when all in..Thanks!
