But still simply exchanging into a property with identical cash flow and all would net you more each month.The key of course is that you do it without triggering a recognition of gain.

Some set rules of 20%, or 30% or a specific dollar amount such as $30,000.

If 75%, what’s a good rule of thumb for cash flow?

I'm not sure what market you're in but you might want to do some research and find out if the 1% rule is common for rentals there.

Doesn’t come close to the 1% rule.

One owner in town finally gave up fighting the city and sold a building they were breaking the rules with.

Any remaining dues follow the "first in time, first in line" rule and will fall in order based on when the hoa recorded their lien. 

If you have a lower gross rental income per bookings (say $150 average booking for a small condo) and a similar $20 cost per basket, but that basket includes nothing that is tied to the identity of the property or makes it unique, it seems likely the repeat booking rate and likelihood of positive review will have minimal impact.

And expenses were not included in the Brokers packet so I am going on a rule of thumb of 50%.
