I told them they could stay there at no charge till the bank evicted them and made them sign a hold harmless.

True that. 99% of people will stay on the internet, analyzing deals and doing research but when the time comes to pull the trigger on a deal they'll do absolutely nothing. 

If they haven’t been paying and causing problems why would you want them to stay?

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.  

Try to stay close to the median home price for that city. 

If you're looking for appreciation you should stay in Vegas.

The company has too many clueless Tax or Attorneys...Stay away, they will tell you that what are you doing is under Foreign Laws while charging you $10K for useless advise.

@Marc Shin ask every guest that stays with you for a 5 star review after their stay.

My first impression is that your numbers in the current economic climate seem a little rosy.I also have friends that are builders and I try to stay in touch with them on costs as we mostly do "to the studs" renovations when we buy a place.
