Is that a dangerous sign? 

Ok thank you I understand the distinction now.

From my POV.it really depends on asset class and tenant Class.. this is a huge distinction. my clients that I sold apartment complex to in Oregon with B class.. they pay 4% but then have to pay for on site manager as employee.. so 4% to manage the on site person so that person does not rip you off :).However for BP and I have to think the vast majority of the rental property investors on this site that have gone to  D C B out of state markets.. those props are not like a 600k rental in Denver and the tenant that comes with it.. or really any city with a A class tenant..

Even the best trained horses can be very dangerous.

To clarify, the biggest distinction between a second home and a rental is the 10% down?

@Greg H.thanks for the feed back and the distinction between and automatic acceptance and the possibility of an acceptance - that is what I was missing.  

Fear (not financing) is one of the biggest danger with REI.

Perhaps the words "retroactive" and "reverse" are too similar for your mind to draw the distinction.
