If you are skilled in each of the areas above, and you have enough in reserves to cover the costs of when things do not go as planned, then you can likely attract money from private money lenders who want to get a return on their money and they see lending to you as a low risk way of earning a better return than in the other passive investing options they have. 

Some of the other lenders mentioned in this thread are more so private lenders / hard money lenders and while they may underwrite based on DSCR, I don't think it is the DSCR loan you are looking for.

I've closed a bunch of loans with Kiavi, Roc, and a few with ABL, I also closed with RCN, Easy Street, Lima One, and some smaller private lenders.I've come to the conclusion that the experience at the lender is not globally good or globally bad. 

I went to 35-40+ different markets a year each year from 2014-2016 to scope out places to lend privately.

Private investors want to invest in deals they believe will be profitable.

I imagine others don't like that it's in an older condo building without private laundry.

They are on a big push to get back in the game though, have you seen their recent ads stressing that they only list private homes?

Quote from @Collin Luckett: I have a couple houses I’d like to put under contract as fix and flips and would like to you private money lenders to help fund.

Whether it's a private chat group, email support, or regular check-ins, make sure there’s a way to get ongoing help.7.

In our still relatively limited experience, seller financiers are usually looking to get a higher asking price in exchange for the favor of the private loan.
