Mold The Real Estate Deal Killer

Mold Creates Real Issues For Home Sellers

Mold in a homeMold in your home is not something you should take lightly, especially if you are planning on trying to sell. Even buyers interested in a fixer-upper will often steer clear of a house with obvious mold problems, because there are simply too many unknowns.

The problem could be easily resolved, or an issue so big that it is going to be a huge expenditure to fix. In the minds of most buyers, it is easier to just move on to other properties without mold issues. In fact in some buyer's minds if they hear you have mold they may back out even if you agree to remedy the issue at your expense!

The Dangers

Black mold is known to cause problems in certain people, especially the young and the elderly. The byproducts of this mold’s lifecycle can create discomfort in humans, including sneezing, coughing and runny noses. There have yet to be any scientifically proven connections made between the presence of mold in a home and more severe medical conditions, but it still worries homeowners.

This worry is enough to send most buyers elsewhere. Mold without question is not something you want to treat lightly. In a Real Estate transaction being educated about mold can go a long way in both easing a buyers fears as well as your own understanding about moving forward and dealing with it.

The Solution

As a seller, you do have the ability to address a mold problem – especially if you start now, before you put your home on the market. There are mold remediation specialists out there who can help you do a thorough cleanup to remove the majority of the mold in your house. You can get the problem under control, and make your house marketable again.

It is important to keep in mind that it is possible to find mold in just about every home. However, problems like poor ventilation, water infiltration through the roof of the basement, and flood damage can all create an environment where mold grows to unsafe levels. Spending the time and money to make appropriate repairs can do a lot to eliminate any further threat of mold. Make sure that you check around your home before you list it for sale. Check your basement and attic as well as closets in areas where it is difficult to spot. An ounce of prevention goes a long way.

A few months ago during a Real Estate transaction in Hopkinton Massachusetts, there was mold discovered in an unfinished area over the garage at the time of the buyers home inspection. The garage had a finished and unfinshed area. The seller at one time had an in-home office over the finished portion of the garage. The unfinished area was used primarily for storage but the seller did not visit the space that often. Sure enough the buyer was in a major panick about the mold being discovered and wanted it remediated by the seller. The seller agreed to take care of the issue as they did not want to see the sale fall apart.

What is ironic is the mold remediation company said that is was very old and not active mold. His recommendation was to do nothing with it as it would have no harmful given it was not active and also in an unfinished area where it would pose no health risk. If the seller has paid attention to this before putting their home on the market they could have cleaned up the area and saved themselves quite a bit of money in the process!

Start Now

If you suspect you have a mold problem, start addressing it now. It may take time to get it all cleared up, but selling your home in a timely manner and for a fair price should be motivation enough to get started.

Yes, so true.  Mold can be a huge deal killer, esp as there are so many other options for people to buy.  get it fixed before it's listed or it will never sell.

Thanks very much Debbie and Phillip. Recently I have seen quite a few more homes that have mold issues. The public certainly is much more aware of the health issues.

Bill, This is such a hot button item. Most people just do not truly understand the issues involved coupled with the misinformation, media hype and businesses that are out make money on this condition (hype) it hard for anyone to know the truth behind this.

The first step in remediation is correcting the condition that creates mold. Mold is always present but need some environmental factors to grow, mainly moisture. 

Any remediation that does not correct the underlying cause is a waste of money.

Also I should mention that if you look up symptoms for damp environments it almost identical to mold symptoms.

Here you see from the CDC that both conditions are symptomatic of these health conditions-

Bill, yes, we don't see the termite issues in our area - but mold is surely a big concern. Last year every third transaction I did had mold issue.

See you on Monday.

I agree, that mold is everywhere. But it does matter what kind of mold was discovered at the property.

It the inspector found a black toxic mold( even not active),I would still suggest to remove that portion of wall that was infected by mold spores. It is better safe than sorry.

No doubt Inna. Mold is something you want to take seriously especially if you have any kind of respitory issues.

Posted by Bill Gassett, Metrowest Massachusetts Real Estate (RE/MAX Executive Realty) over 5 years ago

So many buyers are so leary of homes with mold (or potential mold). Mold is a result of moisture, so if home owners have any signs of leaks, or water intrusion, it is wise to get that repaired to avoid this issue. It does take time to clear it up and there are many companies who can assist with this issue.

I could not agree more Sharon. Thanks for your input on selling a home with mold!

Posted by Bill Gassett, Metrowest Massachusetts Real Estate (RE/MAX Executive Realty) over 5 years ago

Bill, it's always best to address mold issues before placing your home on the market. Not to hide anything, but to have it professionally treated and take away and possible point of negotiation and shorten the transaction process.

I have another one for you: there is no mold sports observed in the property, but it found in the air and the dust.....It is crazy! Old buildings can have a lot of surprises( some of them are pretty nasty....)

Posted by Inna Ivchenko, Realtor® • Green • GRI • HAFA • PSC Calabasas CA (Barcode Properties) over 5 years ago

Excellent post about mold, a problem that needs to be taken seriously by homeowners whether they plan to sell or stay.  Everyone's health depends on it.  Have a good day, Bill.
