"low balling" doesn't necessary meet those standards.The way that realtor's generally have to work is provide the seller the true and accurate comps (market value) as well as expressing to them that you could also buy it at a discount but buy it fast, no repairs, etc (all the other stuff wholesalers say/provide).

Plenty of pool tables and most other stuff on FB marketplace. also doing air hockey, dual pop a shot (basketball), skee ball and a multi-cade.

IF you don't have the balls or finances to weather that kind of time frame, go buy some equities or govt debt. 

Hi investor, I have 10 vacant homes for sale would you like to give me a “low ball offer”???

You don't have a choice of the sellers agent and if they are bad slow, drop the ball that is where a buyers agent is effective. 

I would start out with friends and family to get the ball rolling and then ask them to refer you any investors they think would be interested in your service.

Otherwise, you'll regret it.Plus real estate isn't an intrinsic, nor is any physical asset, ball game.

Try to see a ball park of what is possible. 

Active Utilization of Your S-Corp: This is more small ball type of moves.

Once you think you are in the ball park, get connected to a lender that can tell you exactly what you will qualify for!
