My issue was comps, access to a good realtor fix that for me know I can comp my self and estimate repairs, then there was negotiating that will always be a battle that will need improving. Video wise no not really you have to get in the field and make the mistakes trail and error I can make a video all day but my or anyone else experience won’t be the same as yours. Effective way to finding motivated seller is first pre foreclosure, then probates, then divorce, lastly door knocking or cold calling those ugly one that need heavy repair they are all motivated you just have to trigger they motivation it’s not always money sometime and a lot of the time it was emotion house they grew up in or they raised they family or they feel like they letting a loved one down by selling the property and not fixing it.
