We only have 3 properties and have only been landlords for about a year, but during the rehab of our properties we prayed for our tenants health, safety, and prosperity. 

We can always meet up another time but we can never get our safety and life back.This meetup is postponed until further notice.

Just in terms of safety, assuming the rents are really that high, I would think you should have a pretty nice margin of safety.

ACH is simple, bank-to-bank in a few days.I would recommend you stay away from cash/checks for safety reasons, plus cash is harder to track.  

I’m a bit reluctant since I have two small children; however, I could consider a duplex or something that still allowed our safety and separation from said tenants.

Read David Greene's book on Long Distance Real Estate Investing - that will help get your mindset right and help you prioritize what you need to do.

After you have a safety net of about $10-15k, then you could be able to sleep better at night as well. 

I would prioritize finding an accountant who specializes in real estate taxation over one that is local.There are 20+ accountants on this message board who specialize in real estate taxation.

In short, I'd run my numbers both ways; 1) basic facelift, and, 2) update rehab, to see which makes most sense.Market rents depend on a number of factors; safety, proximity to employment, public transportation (if applicable), features, options, finishes and amenities. 

It’s a 4-unit building so it’s not just his safety but also at least 3 other people that could be affected if something was wired wrong.
