Time is money, and delaying a renovation often means lost rental income.

Then it is up to your tenants to stop by and deposit the rent money/check in the account by a certain date.  

I would be surprised if there weren't notices given to both the defaulting End Buyer (You're in default, you must close by X date or we're forfeiting your deposit) as well as the escrow agent (Buyer defaulted, see contract Earnest Money paragraph regarding release) prior to that actually occurring.

If you can save money and renovate and the ARV allows you to pull your intial capital out sooner, I say go for it!
