Look at Scott Tucker from the payday loan scandal on American Greed and Dirty Money on Netflix. 

Businesses with tons of cash: bars, check cashing, payday lenders, casinos, car washes, vending etc.Then the return's contents are analyzed using the Discriminate Function standards.

House care, lawn care, condition of cars, street conditions, absence of pay-day loan shops... basically all the things you look for when determining where to live yourself. 

Quote from @Paul Lucenti: Would you rather have monthly cash flow or would you prefer a quick pay day after 3-6 months?

This is a $2100 upfront money grab from what appears to be a payday loan company.

@James Wise Outside bases, especially on military payday, is one of those places you can find sex providers easily in San Diego area.  

This way I get paid upfront for my work 1-2k plus I know I have another payday at some point in the future if the deal closes.The costs to fully develop a property and sell for near retail usually involves the costs below and takes 2-6 months or more in some cases, but the profits can be huge if you're working in markets where land costs are high:Title 200-400Legal 500-2000 depending on zoning issuesIf wetlands are present AND its a buffer zone project: 2000-5000Perc & septic design if needed 1500-3000Treescaping & cleanup for retail sale 500-1500Selling costs of 6%I tend to stay clear of properties that need more than the above expense items.  

Sometimes making a smaller profit and providing value is far better than holding out for a bigger payday on a bad deal, I like that.

Its was a very nice payday indeed.Now I spent about 50 to 75k up front in marketing to pull that off..
