Welcome to the community and be ready for a huge amount of information at your finger tips.

What is the ARV?

Perhaps he has some tips as well. 

I'm local the SLC area.

I like RentSpree because the prospective tenant can upload all of their docs into the system and the system auto-emails all references to confirm.

While I don't see it on the IRS tax information, if I remember from the conversation with him, I think you have to buy properties that need significant improvement. 

You'd need to call the local township which I would recommend doing for any LTBH.

Partnering with a wholesaler sounds fine, but check the real estate licensing laws in your state before bringing a buyer for a commission.You might consider getting your real estate agent's license and legitimately earn what your skills, drive, and experience truly command. exactly wholesaling or bird dogging is not a life time or long time occupation  RE sales can be lifetime and if your any good at it at about year 10 you should be getting all your sales from referrals and such.

Where can I see (in writing) the max allowable deductibles - both for conventional and FHA? 

If you want me to give you a quote, I'd need to know the address, 1st lien details (type of loan, balance, interest rate), credit score, income/DTI details, and target LTV (can go up to 80% CLTV on the 4plex).
