I have liquid cash and a good bit of equity that I am considering investing in real estate and would like get some feedback on my ideas.    

They do not tend to like working with newer buyers needing tons of help buying smaller properties for a lower commission check.If you can be more descriptive such as your net worth and liquidity, annual income from job or business, total global cash flow, asset type, deal size, LTV with amount you are looking to put down, area, cap rate expected, fully stabilized or value add,etc.All of these things a good commercial broker will KEY in on to see if what you are wanting to do is readily available or you are looking for a needle in a haystack or wild goose chase type thing.If you are looking to find above market cap rates there are REIT's, pension funds, insurance companies that buy hundreds of millions a year in properties that I can call to purchase in 3 to 4 weeks close all cash.

The difference is, int is liquid in your bank, and thus it has more value based on the ability to keep it moving. 

I think this is why internal rate of return exists - I know we're talking about rules of thumb, but if I've got a property in an area expecting lots of rent growth, I can add value in other ways, etc. over the course of a few years, the present value of those future cash flows and any other liquidity events become very important and it could make sense to accept a much lower CoC in the near term. 

Something to keep in mind is that they'll still want you to have 20% of the total cost as part of your liquidity to make sure you cover cash to close, interest reserves, and initial rehab cost.

cold glass, ice clicking in the glass.. ptchhhht, bottle opens.. gobble gobble pssshhhhhht as the gas settles pouring in that black liquid heart attack goodness... glub glub.. and the famous "Ahhhhhhhhhh"?

I've got around $20k saved away right now in liquid cash, but I'm wondering what the right number is to find my first deal? 

(3) or (4), if you have liquidity constraints over the next 2-3 years.
