I have them pre-typed out in a word doc and just cut and paste, saves a ton of time. 

After listing my property (a 4-plex in San Diego) too high in a declining market, receiving no offers after a month even after a 9% price cut, I asked my broker: at what price could he guarantee an offer within a week or two.

If it cutting into your profit, you need to raise your rates to compensate.

I fear that the upcoming bailouts and cash give-aways by the federal government because of the corona virus will affect the markets in many different ways.I am terrified that printing/creating trillions of dollars will cause my $60,000 cash to be cut in half or more in real dollars by inflation.

So....... how do I know if he has my best interests in mind or if he is trying to cut corners to make his life easier?

If you think there are short-cuts to building wealth, you're going to be disappointed.

You cut a check, and wait for the return. 

The toughest part about the renovation is going to be cutting out 500-ish LF of concrete to install underground plumbing in the new units.

But this is not where you cut corners, particularly if you are in a state where the landlord-tenant laws favor the tenant. 

In other words, why not just do it myself and cut out the middleman - which is you -?
