Quote from @Chris Brewer: They’re actually asking more for the property that’s just the number I think I can buy it for.

I've actually had an investor give two of the properties back to me after religiously making his payments for 3 years on time but got a set of bad tenants and could not maintain the rentals. 

You likely only made a down payment of 3-20% ....but you still get to write it off on the full value across 27.5 years.So 400k/27.5 = 14,000 ish a year of a write off where during the year you didn't need to incur an actual expense, no cash outflow. 

I can find the deals through certain websites and other resources, but i hav barely a clue on how to actually pull the comps.

I didn't have enough space in the Title:Novations where the investor uses a Limited Listing that puts them as the primary contact for scheduling showings, receiving/accepting offers and negotiating are brokering without a license.Novations where the investor actually hires a real estate broker to handle the aforementioned for the seller are not included. 

That is like asking how to fly a plane.

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

I've been using Rat X and am convinced it doesn't actually kill them, currently just have snap traps in place.

I am actually an old fart, semi-retired managing my now small real estate portfolio of 16 doors.  

I actually had your underlying question in mind.
