You really don't have to do this to many times before the monthly cash flow puts a big grin on your face.Perhaps I prefer this method because of the low stress/slow pace it allows me. 

Prefer SFH far and away for the following reasons:Easier to rent / more responsible tenant - built in buyer - lower maintenance issues ( tenants typically take care of incidentals )  - larger appreciation  - easier to sell - larger cash flow - low vacancy rates ( 1.2 % average over the last 3 years ) - easier to overall manage  All my units are in Winnebago County with the following averages appraised value  $88,000 / cash flow $312 m / LTV 67.2% / 5+ and 13+ remaining amortizations ( originally 7 and 15 full termed ) monthly expenses $54 m 2018 47 m 2017 so technically net cash flow would be $258 2018 and $265 2017.

Also, is there a credit card that anyone prefers because of the perks or any kind of other information in relation to this?

I have some folks who've expressed interest, so we may be able to sell without putting it on the market.Since we're empty nesters with an older dog (he just turned 12 yesterday), we'd prefer to be on 1st fl for all our sakes.My 5 yr goal is to acquire 2 MFH per year over the next 5 years. 

Lawrence,With your credit score, for a low down payment program you should be looking at a conventional 97% LTV program, preferably either HomeReady or Home Possible as they have better mortgage insurance rates as well as interest rates. 

Preferably driving distance maybe a couple of hours away 

As others have said owning the system via a cash purchase or using one of the many low-interest loan options out there are preferable methods than leasing. 

Would I be better off getting custom documents drafted instead of basic ones?

You really need to have at least one of those, preferably two, and ideally, all three. 

You could be walking away from a good deal because of your financing and personal savings and not the fault of the property.You don't have to put 30% down if you prefer less.
