Refine it as you go and it will be customized to your needs.It's common for investors to get "shiny object" syndrome where they spend countless hours trying to find the perfect tool that will turn them into an expert investor, but that's putting the cart before the horse.

Learning to overcome objections is hard. 

@Taylor Dasch I didn't, but that is a great point and one that I will definitely use in the future if ever presented with that objection again. 

My objective is to purchase a property in the Sarasota/Tampa/Clearwater or St Pete area this year unless there is a better location to consider.

Any concern from owners about not covering their monthly normal lease amount due to low/slow time of year, etc... and how you are overcoming the objection?

What is your objection to having an HOA?

The object of the letter is to get listings

If preservation of capital to the highest level is your objective than money market accounts and CDS etc as previously noted all appear to be adequate possible solutions without knowing anything else about your situation.  

Also my objective is to buy an apartment building near the campus.

Some sellers or seller's brokers won't care, others will and, most importantly, you won't care...it's just an objective offer based on your criteria and market data.
