(Loan program, term, credit score, etc) just for hypotheticals, say your looking at a 30 year conventional on your primary residence with 720 credit, rate could be ~4.75-5.125%  FHA is typically a little lower. 

They want 10% interest, which is about 4% higher than what I can get with my conventional bank. 

First property I bought was an undervalued house hack double.Purchased for 70k with an 80 conventional loan.ARV 160kI then took an 80k HELOC.Next I bought a single fam to move into using another conventional mortgage with 20% down coming from the HELOC.After all this I then discovered the BRRRR strategy.

Also consider longer term conventional financing with lower interest rates.

It may sound nice to pay a 5% management fee but the extra fees can add up to be more than the other company that charges 10% with no add-on fees.

What i used to do to find services like that was to just find those people on google or google maps and give them a try (https://goo.gl/maps/JhUyEFKVXkH2) unless you can get a good recommendation.Typically, i would go over 2 or 3 different ones to see how well they communicate, how reliable are and how much they charge etc.

My lease clearly states only 1 pet, AND I'm supposed to be charging pet rent for that one dog but I've waived it up until this point.  

That is why I never liked buying from other investors or bank owned properties that charge too much in earnest money deposits.

I’ve seen conventional lenders (those selling on secondary market) fund deals like this before.

But my hope is to groom one of these tenants into managing the house and leasing it from me and let him sub lease each room for whatever he wants to charge.
