Quickly analyze properties using the 50% rule (assuming half of rent goes to expenses) and verify rental comps on Zillow, Rentometer, or with local property managers.

You have come to the right place to learn and meet some great people. 

Thank you the property rents for 1450, round numbers yes, so, if I refi and get 130 after fees assuming a 1300 1400 a month payment, this doesn't make sense to me.

I'm assuming it's vacant or will be delivered vacant (you wouldn't be able to raise rents by 50% on existing tenants in most instances.) if so get your agent to run rental comps and assess ARV for the property to make sure your assumptions are solid. 

Assuming your debt is SUPER cheap and only costs you 12% you’ll save $22,800 TAX FREE  So the combination is saving $60k at 12% (or more) is $7,200/yr and $130k in the bank at only 4.5% is another $5,850/yr  so you’re over $13k GUARANTEED instead of a chance to make $7,200 before taxes  

Many see these as red flags, assuming they will slow down the deal, increase costs, or cause endless headaches.

So my response is assuming you are referring to residential lending specifically. 

Hey @Mark Miles, I haven't done it and it doesn't seem to hamper my bookings, but I am assuming that more info is better.

Assuming numbers + deal checks out, can do 30 yr fixed in low-mid 8's, at best on alternative side.

Assuming you have access to MLS (Multiple Listing Service, a place for agents to list deals).1) Look for deals that look like investor-type of deals (e.g. low purchase price, ugly houses, or sometimes MLS will even say what type of financing it is)2) If the buyer's info is there, voila.  3) Otherwise, contact the realtor to look for leads (that will be more of a uphill battle, but you never know...)
