@Jacob Seim The overall plan makes sense, but it depends on personal cashflow to execute it. With the level of detail you've put into it, I'm assuming you've calculated that in. You've picked good neighborhoods. Some of them have become pretty hot over the past year or so.
I see one glaring flaw. You're limiting yourself to 10 mortgages, and you've created a plan to work within that limitation. The 10 mortgage limitation only applies to conventional loans sold to Fannie/Freddie. Portfolio and other lenders don't have that limit. For example, one local investor I know has 120+ mortgages.
Fannie/Freddie and other Government sponsored programs (FHA, VA, etc) generally will offer the lowest rates and best terms. As you grow past them, shorter amortizations become more common (20-25 year).
There are also non-conventional 30 year mortgages that work for BRRRR (short seasoning), or to bypass other limitations (DTI calculations, >10 mortgages). Of course, they are not government sponsored so the rates are one to one and half percent higher.
I just mortgaged 8 properties at a 4.9% rate on a 20 year loan. The shorter amortization reduces your current cashflow, but it does pay down the loan a lot faster. That extra payment is all going to principal.
Once you've moved to Cinci, check out the local REIA. It's a good group of people and you'll find some good connections there. Find me and say "Hi", I'm almost always there.
