@Rohit Kumar good job in looking to move ahead!
You could try shifting out to a suburb or to a close by small city like St Cloud, though with a major rehab I'd want to be there at least 3x weekly, if not daily, and that might be tough to swing working 9-5 and drive an hour each way. Thus, I'd probably go with @Alyssa Strom good advice and find a hard money lender to cover the acquisition, then use 40-60k of your own savings to complete rehab before refinancing out.
Finding hard money shouldn't be hard, you could here on BP, with a google search, by asking your investor friends, or at the back of the bar.. I kid I kid.
I personally feel looking into my crystal ball that the market will soften mid 2022, which should give you some time before refinance concerns.
I used to prefer Minneapolis because I thought it was flashier and had higher appreciation, but I've come to prefer St Paul because it's more quiet and there's no rent control, crazy tenant screening restrictions, or rent control on the horizon that I've heard of..
Do sent me a message if you're ever around and want to get coffee, I'd love to see your duplex!
