Ideally, somebody who has a track record of getting investors good off-market deals.  

I am looking for referrals for an agent that can help get me on track in finding some deals.  

I think you're definitely on the right track.

Not super in depth but I do have a good track record of being honest and hardworking.

Stay away from low priced stuff, 2/1's or 1/1's, blighted areas, rail road tracks, war zones, etc., and apply all other real estate lessons to buying notes as you do to buying the properties.

Tom Chen as per my CPA and asset protection attorney, as long as I can track income and expenses for each property (think Quickbooks or the like), there's no issue with using one set of accounts, especially with a Serial LLC.

I have always been curious how much I spend per month/year and on what, but never got around to start tracking.

All of the overhead that an employee working at a 9-5 doesn't have.If you have someone screening your tenants who has experience and does a great job it can be well worth the fees to avoid a vacancy every other year.I'm an accountant, my clients don't pay me just to prepare a tax return.

Mileage.. would be a self employment deduction, if you didn't get reimbursed and kept track of your mileage I believe you can deduct the mileage cost use.

I would consider 675 for a long time tenant that has a great track record of paying on time.
