I'm not sure it would work in the way you're thinking in the mainland because lending/liquidity is difficult here in this current market.

That's $25k LIQUID not margin. 

While one person “needs” $15k in liquid savings, someone else “needs” $150k. 

The only surefire exit plan is to have the liquidity to pay if off.

We then liquidate these loans, and do it again.Is there any bridge lender here who would be interested in discussing providing leverage against these assets, so we could buy more of them in parallel and scale up?

Some investors cash out when they want liquidity for new deals or need to reduce risk, especially if a tenant-buyer has a history of late payments.

For liquidity, we'd need to see cash to close, 6 months of fully drawn interest payments, and 25% of the rehab budget in a US bank account to qualify.Cheers! 

If the lake is smaller then they might not be too popular if it is primarily a fishing lake.I would also add a general store with basics, bait, beer, food stuffs etc.

Government backed foreclosures get marketed via sites such as the HUD Home Store and Homepath websites. 

Anything around $30K or more usually fits in the budget better under a COR.A Cah out refinance also put liquid reserves/Cash into your hand or into checking/saving and can be used for PITI "reserves" or assets required by most banks/lender to buy more REI properties and a Heloc can NEVER be used as an asset or PITI reserves.
