Hi @Jon Quigley  one of the ways to minimize your risk would be to insert a financing contingency in the contract. 

I'd start with a phone call to the tenants that would end with "If you are out by Friday,  apartment is clean and I never hear from/see you again,  I won't contact (insert threat here:your lawyer the press DCFS, LA child service,  all of the above  etc)" 

In a commercial lease agreement, is there language that can be inserted that mitigates the lease obligation of the tenant in the case of the tenant breaching the contract? 

On a cape we did the large front windows were the old single pane double hung.We had a company here just make two pieces of glass sealed for insulation for each opening.The glass was also tinted.Then we framed the glass inserts in with jamb extensions etc. it looked great & saved us a lot on special order prices.Another one we replaced all the windows with those we could find at a contractors excess stock depot.

These buyers didn't need to be convinced that we did good work (they or their agent saw our first house and liked it) and knew that the house likely would NOT be around forever (they lost out on the first one) -- so they made quick and competitive offers....J Scott - I believe there is a typo in the quoted snippet, with my correction inserted in uppercase bold; correct me if I'm wrong :)

After closing from both buy and sell side (purchase and then resell)that takes it down to around 30K potential profit and then insert private money. 4% origination fee, other fees (inspection, survey, etc from hard money lender) that totaled about 10K ,along with the 12-14% interest payment each month (approximately 1200 per month for 3 months) and you are left with about 14K profit pre-tax.

Insert cars, knives, rocks, electrical outlets, tornados etc.

This is standard in the industry.If you are your own GC, then insert yourself in the GC requirements.If you can not get the subs to provide this, then I always require my title company collect the Certificates prior to releasing draw checks when I use construction loans

I've mentioned branding your company, leaving small details on jobs unique to your work, these are signs as well to those who can recognize them, like small brass inserts in building corners or the hearth of a fireplace.

I usually assume they are typos or they are for rent and they were accidentally inserted into the for sale section
