If they do need financing, then speak with your lender about their new build financing options. 

I was going to do that in an attempt to get creative with my financing options so that there are no liens on it and I could borrow against it as an option.

Example: you can option to have a fireplace with two windows on either side.

Curious why you want to focus on multi-state and not close to home?

What other options would be good?  

@Collin StewartSince you're PCSing to Columbia, SC, and have VA loan entitlement remaining, house hacking a small multifamily with a VA loan is a strong option since it requires zero down.

Quote from @Rory Darcy: Hi guys my name is rory, pretty new to this im an out of state investor residing in new york, looking to invest in wisconsin and illinois, currently looking to build my portfolio around multi family duplexes or single family residencies, would be great to connect with like minded investors or agents who can lend a hand.Rookie investors should not invest out of state.

As for financing, make sure to explore options for using rental income to qualify, and be prepared for a 20% down payment.

Looking forward to reviewing these options.

If you can make a conventional loan work, it’s likely a better option.
