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?

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

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.

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.

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.

As a former IT professional I would not recommend storing passwords in any solution that was not designed for that purpose.

Personally I would not liquidate the stocks, just maybe only contribute a smaller amount to it on a monthly basis.As far as the car, I would pay it off from current income.

There are obviously other requirements about project scope, liquidity and FICO that come into account as well, but we can do it! 

Another builder told me they always use RTA, and buys them from the big box stores.
