You should consult a tax professional for an answer based on your unique situation, this is not tax advise just general information.

If a single-family owner-occupied property is worth $400,000 - I wouldn't invest more than $280,000 (70%) in a note secured by the property.ITV takes priority over desired yield - so even if the note discounts to $350,000 based on desired yield, the investor still won't go beyond their maximum ITV. 

I think some folks search for discounts so that's a way for being promoted.Seems guest dont rent a 4 bedroom house unless they have triple the amount of guests they originally reserved for.
