As a private lender myself, I can offer some different points of view. My partners and I view ourselves as partners to the real estate professionals. You do what you do best - finding good deals and get them done, we do what we do best - provide the funding so you will never have to worry about it anymore.
Private lenders lend base on the value of asset ( profitability of the deals ), not your income, credit score or your total liability which conventional financing base on, of which eventually you will run into some sort of walls if you are successful.
Think about this, how many deals are you doing right now, image if you have unlimited funding, and you can close the deal whenever you need/want to, how many more deals you can do?
Also, we have vast network of real estate professionals, we can provide not just funding but other value add as well, like bring the deals to you. So, it's really a win-win situation if you are working with the right lender.
Just my two cents.
