great investment opportunity in Brooklyn

HEY, have two lots I found. In carroll gardens Brooklyn. The lots are 20x90 and have a car mechanic shop on it now at 20x55 each. They can, as is, easily fit 30 cars each. Parking goes for 500 a month each vehicle! It can also be torn down and made into bigger parking or residential units. Zoning allows for 6 stories. How can I get my hands on it with no line of credit or does any one want to take it from me for a 5 percent birddog commision
