We live in Central California.

OdoBan can also be used on some fabric and as an air freshener.For the walls and ceiling, wash them down with a mixture of vinegar and water.

Does the house have central heat, or does each room have to contain its own heater?

leave a bowl with bleach/water mix sitting in each room for at least 24 hours (removes smelly air) open windows ASAP upon your return.  

The good meters will run you $380-ish.Have plumbing repairs in past included installing "Studor" vents or air-admittance valves in the venting ?

I am in the heating and air-conditioning industry and am currently in the process of starting a residential business.

Along the coastline from central California (those in the bay area. think they live in northern CA but don't) south to San Diego have areas with extremely expensive real estate.

Typically, they say that anything over 80% is air - meaning that the top 20% is eaten up by commissions, lower than asking price offers, closing costs, other things that buyers want done etc.If you buy at 63K, put 40K in and ARV is 120K - you're at about 85%

I just finished reading Buy and Rent Forclosures byJoseph Neilson.Mr Neilson advocates stripping houses of central air, garbage disposals and many other amenities in order to eliminate maintenance costs.My question is, wouldnt garbage disposals cut down on clogged drain service calls?

Make sure air is coming out of all the ducts in the house.
