How could I structure a deal that would sound acceptable....   

I have three sets of cleaners and they get the offer to accept the job in order of my preference.

@Luke Rusten have personally used a higher price to get sellers to accept my seller financing proposals many times in the past!

Not trying to pick a fight here, but these forums are quite impressionable on new or inexperienced real estate investors and don't want those who read these forums for educational purposes to believe they should expect or accept 1/3 deposits as the norm. 

All of our platforms do not accept vids and our site is not optimized for them. 

Only way I will lock myself into 1 is if the exit fees are not prohibitive and % basis points is within acceptable ask price from the present lending rates, can surely go in for a higher deposit to tilt the balance towards positive cashflow i.e 25%-35%.

Did you include an acceptance deadline? 

Quote from @John Federic: I ran some numbers for you using the Cashflow Analyzer Pro from AssetAFC.com (see the attached picture).From my perspective, this deal still looks acceptable, even though it won’t cash flow in the first year, assuming a 5% vacancy and 5% for repairs.

Some states do not allow RUBs due to the inherit unfairness of the allocation of the apartments' W&S  expenses .Although sometimes not economically feasible in older properties, water sub-metering is practically unanimously accepted through the US.

Accept that the successful RE investors have a well developed skill set that is not immediately acquired.
