Buying property from family

[Account Closed]

While searching for my first investment rental, a family member offered to sell me their home (single family) for the amount of their remaining mortgage which is roughly 200,000. The home value has been assesed at 322,000. I would treat this as my primary residence. I have 60-80k to put down.

I was hoping to get some advice about how to do this deal. Can i legally buy the house for 100,000 less than the assessed value? I have read that if a home is sold too far below the assesed value, it can trigger fees for the seller which i also don't want to do.

This is a great opportunity for me and would like to move on it asap. Thanks?
