I read body language and although they are very charismatic.... they failed my test!

And for some English is their second language and they would fail a test immediately. 

I think that part is going to depend on the specific language in the contract.

If no violations are found during a rental inspection, the L&I Commissioner may delay the next required rental inspection one additional year from three years to four years.Change the fee assessed for a second rental re-inspection from $25 to $125.Add language reiterating that regular rental inspections are a condition of a City rental business license.Add a civil fine of $500 per rental unit for failure to register/obtain a rental business license.Add a civil fine of $250 for each violation of the housing code if the violation relates to a rental property or a vacant property.

Also, you must pardon my messed up English, not my first language)Thank yall!

This is how you discover things like "Unit 1's rent is $800/mth, but the Vendor is only collecting $600 because the tenant vacuums the stairwells and shovels the walkways.When the Vendors story and the tenant's story to not align then "Luuucccy ... you got some 'splaining to do"Thanks for the language lesson but my point was that it is the tenant, not the seller, making the statements in the estoppel letter. 

I have a seller that wants me to remove the language from the purchase offer that would allow me to back out of the deal but I'm hesitant to do it for obvious reasons.Anyone have any creative ways to help protect myself if I remove that language, for instance can I add a line that lets me reduce the purchase offer by any amount I want should my inspection produce unfavorable results?

All payments made by Tenant to Landlordafter the tenancy commences, no matter how designated by Tenant, will beapplied as follows: first, to any outstanding amounts due for damages/repairs,utilities etc.; second, to any outstanding service charges and fees from priormonths; third, to any rent outstanding from prior months; fourth, to anyservice charges or fees due in the current month; and lastly to the currentmonth’s rent.  

I want to become fluent in this language!

If it was a quality referral not in my network and they were buying a bunch of commercial properties that might be different.You have to watch for the referring party trying to use language that you will pay them a fee on the current deal and all future deals (perpetuity).If you do think of accepting a lead only pay for it if it closes and nothing upfront!!
