(The Wall Street Journal, in the last 12 months, has had articles, that real estate in Florida, which is a goodly number of feet, above sea-level, is now selling for high prices, & intended to be built on, by the wealthy, as refuge from the rising expected ocean, which surrounds Florida.)

Be ready to jump to a new management company.I am now using two management companies (each managing different properties), essentially to have redundancy in case (when) one of them stops functioning at an acceptable level. I

Any AOS can be found online or with a local attorney. 

Now the secondary question that may indicate a superior skill level is:  is the market bearing the filter? 

If the occupancy level is low, the sellers will think in terms of Cost to build, versus revenue stream/NOI. 

Investing in real estate at the individual level is a bit more esoteric (which leads to market inefficiencies) and allows you more control over the asset. 

Otherwise include a contingency as others have said that leases will be provided to you within X amount of days of both parties signing AOS.

Before, given my status and revenue level, I would call and speak with a high-level rep who would ask the right questions and would understand the situation from both sides and make a fair judgement.

Having a number in mind is totally reasonable, and discussing strategy, especially at a high level, is a really worthwhile aim for these forums.As an aside, my goal is $25K/month in ten years.

That is $700,000/year, your wealth tax on that building is $20,000/year, you pay federal taxes at 37% on the profit that property produces, say that is $500,000/year in profit, your tax bill for the federal level is $185,000 plus the state tax of 13% which is $65,000.
