If you're willing to roll with the fact that some people will be dishonest about group size in order to avoid the extra charge, then sure, why not, but you'll make yourself nuts if you want to enforce it 100% of the time.

Mario Robert is a dishonest and conniving individual and Bridgehouse America is a complete sham of a company.

how did you determine they are dishonest

At that time my contractor (who I later found out in another project that is dishonest) told me he pulled permits.

The only way you can achieve what you are looking to do is by being dishonest on your mortgage application - and mortgage departments are going through things with a fine tooth comb - after all they are not exactly inundated with work at the moment!

On Wednesday night, they responded they won't do anything (Fine) but also they are "Not sure if the tenants will move out after all" *Obviously a deal breaker.My realtor recommended we walk away from the deal now, and that the seller and listing agent have both been pretty unresponsive and dishonest about the status of everything, which doesn't bode well.My inclination is I don't walk away unless they can confirm in fact that the tenants will NOT move out (That is a deal breaker, these are not quality tenants that I want to inherit)- and despite we were planning to close Feb 6, we could give it a bit more time.  

You probably are not insured for short-term rentals so this could put you at risk if something goes wrong.You also have to consider that your tenant is willing to be dishonest and essentially steal from you.

Bills for things that didn't need fixing are the result of a dishonest contractor.

Dishonest?

I think it is bad practice and a bit dishonest to offer a higher price and negotiate based on an inspection. 90% of asking isn't unreasonable, especially if properties have been sitting on the market.
