We gutted house installed a 98% energy efficient forced air furnace multi stage.

I'm a contractor,& have worked with Realtors extensively.have your Realtor ask around the office for someone that does repairs/inspection punch list items, they will be able to clean up that mess for you at a MUCH lower priceYou most likely won't have black mold, but Dawn dish washing soap will cleanse everything of mold"Home inspectors will verify"secondly, after all the moisture,& suspected mold has been cleaned/dried, you can simply use good sealer/primer on wood,& concreteI would guestimate around $3,000-$6000 for the entire job including hardwoodsMake sure you block any air intrusions in the crawlspace areas, Colorado can be hard on water lines :O}

There were major/minor repairs that has taken place in the 3yrs (A/C unit was converted to central heat & air had to be rebuilt twice) among other things.

When I was able to finally track him down through one of his references (he answered his phone by mistake) I learned he had signed a lease with another property and had no intention of letting me know this, leaving me hanging in the air over this issue.Gail

My timeline is still up in the air, but I'll be able to pull the trigger one day. 

Tyndall Air Base is top notch also.Good luck.

Currently I serve in the US Air Force stationed at Hurlburt Field in NW Florida.

I almost at a point where I don't even bother with home inspectors.Some other common issues with older houses, particularly if you will be renting:  lead paint, asbestos, mold (although I find older houses are leaky enough that, as long as the roof drains well, air movement through the building is good and prevents moisture buildup), steep staircases, narrow hallways.But you MUST MUST MUST do a walk-through with an experienced contractor (one who specifically has experience renovating older houses/buildings) prior to placing an offer.  

I would think you need sales comps for both ones with central heat and air and those without.  

The units are all central air.
