It's my understanding that certified mail must be signed for, and for a PO Box, that should mean going to the Post Office clerk with a note they leave in the box, showing ID and signing for it.   

Can you give me an example with $$$’s?

Remember its loan to Value so that means you can go up to 90% Loan to value. 

Keep in mind the private lender is probably going to want a second mortgage for the investment so you'll have to address that paperwork.  

Wholesale should never be done with a listed property unless you give 100% full disclosure up front so the agent and seller knows you have no real money no real means to close unless you can find a buyer etc etc.. but of course here we are talking about this and poor wholesaler cant get deals LOL

Now it's well over $2M.As a result, buyers of moderate means were forced out in concentric circles. 

@Jose Jacob Does this 1% here mean the percentage of the total cost (buying price + renovation).I see a lot of 90K houses but they might need another 40K in renovation.

If you can't keep control of your personal finances, you are highly unlikely to succeed in real estate investing.

Plus with the prices of land and construction nowadays you would likely be in jumbo loan territory, meaning higher rates, and down payment requirements.

You keep a fractional reserve, plus credit reserves, plus liquid assets, and the rest of the capital goes into the real estate deals that really drive the return for you.
