It's better to give unconditionally than receive.

if anything every single person coming to this forum is welcomed unconditionally and consistently shown acceptance and assistance anytime they seek it.

Then again we want unconditional time set for us wen investing?

I have two different break-lease options for people - they can break early with 2 months rent (one month plus the deposit, assuming there's no damage), and I will let them walk unconditionally - I reclaim utilities, yard care, etc.

But if it's only $600 then you could do better.What I would do is get a contract on it then get a valuer in and get another agent in to tell you what it should sell for and what work needs doing. if everything stacks go unconditional, otherwise walk.Properties don't sit in Glenfield there HAS TO BE A RESAON they are willing to give it away like this.

I come from a place of understanding this and unconditionally accepting it.

One last thing, because I’m in the construction management field and deal with finances as well, I like to reduce risk wherever possible and I’d suggest looking into state specific forms to have him sign since you've already paid him: (might need to consult with an attorney for the verbiage, just depends on what you can find online): unconditional release of received paymentsreceipt-release and indemnity agreement a sub-tier/third party release lien release form These would all cover your end for the money you’ve already paid out, so that he can’t come back after you for “lost money”, or if his roofing sub comes back to you saying they were never paid. 

I only look to unconditionally enforce my early termination fee with an eviction otherwise I will negotiate with the tenant.

That's where bad experience/nightmare come in.Lastly, to answer your question, to build a basically designed, square/rectangular house without crazy jigsaw puzzled cuts on roof, the following price is a good competitive construction only price for what you need to do:Around $165 per sq ft on conditioned space (for an average 1200 to 1800 sq ft house, 8-9ft high ceiling, everything is investor grade finishes), $90-100 per sq ft for garages/unconditioned storage, $60 per sq ft for porches/opened spaces.  

Just curious, what is your take on this line  however, this section shall not apply to irrevocable gifts, to unconditional contracts to purchase, or to options based upon a substantial consideration actually paid and not subject to any agreements to returnWhat is your opinion of that excerpt in short and in its entire context?
