The solution here IMO, if you are comfortable with your feasibility analysis, projected NOI, and the overall project risk: is to find a partner.

I use Rent Recovery Solutions.

They are based on the contractor's, and your rant is justified. 1099s are indeed a clumsy and ineffective solution to combat unreported income, and it does create an undue burden on business owners, including the burden to inquire about your contractors' business form.The only part of your venting that I disagree with is the risk of disclosing SSNs.

Luckily, we have attic ladders for a simple and convenient solution to start enjoying that extra space you have.

What's the best long term solution for this type of problem? 

I don't claim to have answers/solutions for any of this, of course, but I am glad to see it being acknowledged and discussed here.As far as Denver- I was one of the artists moving into 80211 in the mid 90's.

In AIR leases, the most common form leases used nationwide, that provision is at 150% of base rent.If your lease does have a holder over penalty provision you could use that as leverage to enforce prompt payment of the "base" rent.Otherwise I agree with the mention by another that if he's not willing to renew the lease and pay his rent on time then you'll have not choice but to employ the service of a towing service to monitor your parking lot.FYI, most commercial leases, unlike residential leases, have a grace period of ten days.

The solution may not be found here but elsewhere.

With the construction loan, funds are closely monitored and before a draw is released it must pass inspection and would protect me.

I know this b/c I voice recorded our initial consultation in which you stated "there are other great solutions besides your current strategy".2.
