Would the construction lender allow the $250K to be in second lien position or are you looking for and unsecured $250k loan?

They provide unsecured funds within 3-7 Business days once qualified.

really depends on who much capital you have.those with small amounts of capital >100k  might invest with a HML who does not put you as a bene on the loan so your unsecured just in the deal. 

(he said he's ok with this since this would be an unsecured loan) The purpose of the loan would be business expenses, growth through advertising and for new route listings.  

The buyer took 10.5% total unsecured loan.

As the example showed, leveraged RE typically outperforms unleveraged S&p by a large margin. lots to learn but you currently have an unleverage RE asset but want to start in RE investing.  

I take it to mean you have someone willing to invest money into an entity you own as an unsecured note at 5% interest plus a cash flow participation on property you purchase?  

No lender will finance a property in another country, unless you can provide collateral from your home country or you’re a large company and the lender will give you an unsecured loan based on your balance sheet but, anyway, both options would defeat the purpose of getting leverage through the purchased property.2.

Just yesterday I had the same conversation with Jessica LaRusso at Seek Capital and they also offered me lines of credit through un-secured credit cards, offering 0% interest for 12-18 months. 

You can use credit cards or an unsecured loan.
