Right now the two units I have share one.

I agree with John, we are seeing renovation costs of $150k- $200k for a basement unit and $250k + for a coach house. 

Right now I own a duplex, I live in one unit and rent the other for $1400 per month.

Single family, 2-4 unit? 

DSCR loans are used to finance the property once you have tenants in the units.

My wife has 2 rental units and I have one rental unit, each rental unit is in their own LLC.

We invest in Greene County, Ohio and currently have 24 low income units. 

If you're willing and able, I do recommend the "house hacking" strategy which is just a fancy name for buying a rental property and living in one of the units, because you'll get very favorable financing - an owner-occupied fixed-rate 30-year mortgage.I'd also say, analyze that property as if you won't live there and it's a pure rental, and make sure the property is still cash flow positive if there's a tenant in your unit because then you'll know if it's actually a good investment.And when you analyze it, include payment of a property manager in your #s because if you don't, and doing so would make it go cash flow negative, then you've just bought yourself a job because you literally can't step away from managing it without losing money.

House hacks are fairly straightforward regardless if the units are separately metered.

Asking price is $998,0002 duplex units on 1 acre in good location.It's been on the market for a while, so I believe we could offer slightly above $900,000 and be considered.I would increase the rent after updating each unit.
