@Andrew Tudor If you haven't already, go to http://cagisperm.hamilton-co.org/cpop/permits/address.aspx and plug in the property's address.

If yes, were they permitted?

Measures like; Job growth, building permits, crime rates are pertinent for these types of evaluations.Good luck - Ned

(Not sure if permitted) 998 sq. ft.

installation requires a permit, and permit requires an energy form calculated by the A/C company.if you just need either the inside or the outside unit replaced, make sure the old unit that remains uses the new R-410A freon (since 2010), not the older R-22.  

Make sure you are permitted to do this inspection, don't just assume you can!

I think financing is an excellent way to grow your business, but to grow too fast without having reserves for the rainy days could be like you said in your article, disastrous.I'm currently exploring options to refi and cash out one of my free and clear because the property value jumped more than 100% of my purchase price + repair costs.I'm looking at: 1) acquiring another income generating free and clear with the proceeds2) trying a flip, and applying what I know about the planning, permit, and construction aspects to my advantage.Both are leveraging up, but with option one, I'd still have piece of mind that there isn't a big loan attached to it.

Its a big job and requires permits and inspections, so its expensive.

If it is cheaper to demo and replace (don't forget plumbing and associated permit costs), then why not take the approach that makes you more money.One other thing with old tubs.

We are building a house in San Clemente, (it's in for permits right now) and are planning another in Capisrano Beach, then two condos in San Clemente.
