where to find land deeds records

One way is to use the FS Records option and search for DEED or LAND as a keyword

https://www.familysearch.org/search/collection/list/

also

if you can isolate to a country/state/county - you can probably find answers to your question in the FS Research Wiki

https://www.familysearch.org/wiki/en/Main_Page

for example here is the Research Wiki Page for Bingham County, Idaho

https://www.familysearch.org/wiki/en/Bingham_County,_Idaho_Genealogy

You may also use the FS Catalog to look for books related to deed record

here I did a search of Idaho Deed Records
