I pay $875 (including principal, interest, taxes, and insurance) and rent it out for $1,625.

After the head start period and hopefully getting a couple/few?

Just make sure you reach out after applying because they don't reach out to you very easily.  

In your opinion, would someone be considered an expert after completing 2-3 'smaller' multifamily deals, or is it more like 5-10 deals?

My question is: when wholesaling, after finding a great deal, do you need real proof of funds to the get the property under contact or is there a way to get it under contract, find a buyer and complete a double closing/assign the right to sell without actually having the cash for the property? 

After 24 hours, you throw everything into a dumpster.

And it can work really well for you as long as you pay attention to the statute requirements.In order to defer all tax you are selling investment real estate and buying investment real estate of at least the same value you sold. 

After I gained a lot of experience, I was able to do more deals using other people's money.  

After writing really nice ( what I thought was nice and helpful responses) nary a thank you..

Assuming property taxes + insurance added don't go above $1,100 total, you could maybe make this work.
