Since you have more cash available you can then even with limited financing available in a down turn can take advantage of low priced deals.In another example if you have very to little debt on properties when lending dries up will be harder to access a good amount of your equity with a loan to take advantage in down cycle to buy more properties.No strategy is fool proof  but does make sense.

You need: 1) a solid, foolproof way to estimate so you actually make money, 2) a comprehensive and exhaustive Scope Of Work, 3) a good looking Proposal, 4) a legal Contract for your state that protects both you and the customer, 5) Change orders that document both cost and time increases, 6) professional invoices and receipts, 7) all the appropriate lien releases etc.Actually knowing to be the perfect carpenter comes a distant second......
