If, however, you're coming in with a very thoughtful and transparent offer showing that you and your agent are a pro who have a true reason for the offer, the seller and listing agent are much more likely to work with you.

My spider sense says this is on the "too good to be true" side of a scam vs. not a scam.

NOT TRUE.

@Shannon L Fogarty the tried and true technique here is to ask other investors in your market who they are using.  

But of course, a realtor is your friend in refining that true ARV. 

In general, it is always good to look at the taxable value every year for your property while you still own it when the tax statement comes.If you feel you can support a lower taxable value with sold comparables that are like your property nearby, then it is worth your time to try to dispute the value.It is true there is a very short timeframe to schedule a time to go in and dispute the taxable value with your local property tax assessor usually and the deadline is printed on the annual tax statement.The reality is real estate does not always go up in value.To your success!

Is this not true? 

Building a true buyers list requires networking and effective marketing channels, especially if you have the capacity to expand beyond your local market.

The same is true for home warranties.

I lived there myself before so I knew it wasn't true but was curious.
