About 98.99999999% of them.

Quite often - I sell a lot of homes in our historic area so, that's more the 'norm' for me. 

We have a contract disclosure for that in CA and buyer would investigate as part of their inspection contingency period for pre-1978 Homes. 

‘We have many homes that fall within that era in the Los Angeles area.

Every day just about. Homes in the center city here are mostly built 1890 to 1920. The next ring is 1940-1970 and suburban areas 1980 to brand new. 

Over 50%.

And have NEVER had a lead-based Paint inspection or analysis.

As Charlotte is the kingdom of new and newer homes, I don't all that often... but when I sell those homes there's never been any untoward concern. People sign disclosures. Have never had a buyer who opted for an inspection.

We see them everyday, you can assume that they all have it, but it was likely covered up decades ago with non lead paint.

If it is pre 1978 the owners might not have had the house tested for positive proof, but all the paint back then had lead in it.

Lots of them in this area. the 20 houses closest to us were all built in the 50's. Some were built in the 1800s.

Not too often.

Often. Current owners often do not know whether there was lead paint in the past, since many haven't owned the house that long. Most people do not schedule a lead-paint inspection. 

I'd say all of them. I've never had anyone come out and say they had it tested for lead paint.

It is common.  I never had anyone do an inspection... just signed the disclosure.

In Florida, not too often, but there are instances where it shouuld be done. In Chicago, much more often!

It is a daily occurance. I would say that it's not intelligent to figure that a house built prior to 1978 does not have it. Proceed like it does.

Our newest concern here is asbestos in old floor tile.

Very often.

Not very often Praful Thakkar 

Not many.

Probably about 50%.

Its going to depend on the particularly area... we have had lots of properties built in N. Va after 1978 for sure but quite a few older established areas as well. So it will just depend on the neighborhood.

Routinely!  And I've NEVER had anyone who truly knew and have never had a buyer care to spend their time or $$ to find out if it's buried under layers of newer paint. 

Hello Praful.  In our area,pre-1978 construction is common. It is a discussion a d the decision to "complete any further due diligence " remains with the client.  It is typically a non-issue for most but it's up to them.

 It is likely that a home built prior to 1978 may have had lead-based paint used on it. Unless a specific inspection is done, no one knows for sure. I don’t recall have such an inspection done in my 20+ years as a Realtor.

I had one client who checked “yes” on the disclosure form to the question “Do you know if your home has lead based paint?”. He owned a paint store and his home was built in 1960. He said, as a professional, he knew that his home had to have been painted with lead-based paint.

Lots of them.   

Always "unknown". 

I am gathering that in your area, there are not that many.  We have a lot of them.  A

Rare. Some of the homes I listed as part of a probate estate may have had lead-based paint.  

Almost all of the residential transactions I do! Old historic mining town most of the houses are pre 1978. Not very many new builds here. 

In TX, we have a required lead based paint addendum for homes built prior to 1978.  There are two check marks (seller has knowledge of lead based paint or seller has no knowledge of lead based paint)  Everytime, I encounter this form, the later has been checked.

I assume that all pre-1978 homes have lead paint. In fact, I think that all paint pre-78 had lead in it.

Not too many.  However, typically, owners have changed many times over the years so it's usually "unknown" to the current sellers. 

In the area I work most homes are ast least built in 1990 so not common.

8/10 properties and never a lead based paint inspection.

Don't gnaw on your walls and you'll be fine.

they come-up and the appropriate paperwork & disclosures follow

In New England, quite frequently. Actually, it's often pretty certain that lead paint was used.

Funny you should ask Praful. Anything built in the 20th century is old to me and rarely do I come across them. Yesterday, however, I filled my annual quota with four showings all built prior to 1973.

Every time.

I selll quite a few pre 78 homes and no lead based paint tests have ever been done that the sellers are aware of.. Most didnt do it when they bought...

So in answer to your question, often

A couple of times a month...

In my area at least 50% of the time

Most sellers answer the question unknown because they don't have any facts.

On the EAST COAST - ALOT 

I mostly sell newer homes.  There are several pre 1978 homes in our community and I've sold some. I never know the kind of paint used in a home.

I do not come across many that have lead reports. I believe many are aware of the strong potential of lead paint presence. 

Pretty often, though most simply assume their is lead paint at least under layers of new paint and don't test for it. -K

Very often.  Only one have I come across where the original owner was selling the place... sadly, she had alzheimers and the disclosures were a moot point.

Never seen anyone do a lead paint test, if there was any lead paint, it's been painted over so many times by now most people don't worry about it.  I'd actually hazard a guess that many don't even know about lead based paint's dangers.

This happens often and typically the answer is "unknown."

Praful Thakkar A lot of disclosures signed in my area.

it's usually a good shot that there is lead in the paint.... but we see "unknown" checked often....  any buyer we work with would have that inspection....  

Some...but not many...
