Giving proof of funds and a bio can help, but the buyer that offers more often times wins anyways

Are there still plenty of good LTV’s out there from motivated sellers or are they harder to find now?

You may be able to find someone to partner with who can provide the funding while you do the work, then split the profits and move on to the next one....

No funds available

I want to know how you started out with your initial funds, was it a loan?

You could go traditional mortgage to qualify for the purchase, and possibly find an investor willing to go 2nd lien position -- to what LTV they're comfortable lending up-to in 2nd lien position is the question. the higher you go in LTV, the more difficult and pricey the 2nd lien would be. with that said, I have seen 3rd lien positions as well, but not exceeding 65% LTV. 

I send a proof of funds (bank statements) with all offers.

@Raphael Turner  You would be able to go up to 75% with a conventional cash out refinance - that would pay off your current loan and you would keep any funds left over as cash out. 

We purchase 1st lien residential notes for hedge funds and banks.

So, keep a good fund in an emergency operating account set aside for rehab-rainy days.
