I'd recommend not taking a max cash-out if it's not needed, but to take out what you need +10% to give yourself some breathing room.

I would not recommend an OOS BRRRR for your first BRRRR.  

Welcome to the site @Alyssa Henderson!

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I could also leave a unit within the multifamily property vacant when I am abroad to use for storage if needed, to better help solidify the "primary residence" requirement.This is a pretty specific question, so I haven't been able to find any previous posts on it or any helpful literature online.

I only have student loan debtI have a full-time remote jobI have no prior experience in real estate investingMy credit score is high 700'sHere are the details about the property in Zenda,WI:Asking price: $235KIt’s being sold by out-of-state heirsIt needs at least $50K in repairs and updatesThe neighboring house recently sold for $235K (though I don’t have details on its condition before the sale)A family friend who owns a construction company assessed the property and noted the following:Replacement Needed: Furnace, Water Heater, Water Softener, Floor (concrete replacement needed due to unevenness), Roof, GuttersUpdates Needed: 1.5 BathroomsConcerns: Black mold and water leak marks upstairsRemodel Suggestion: The staircase is very steep and narrow; recommended to relocate and extend it into the living spaceAdditional Work: The property slopes downward, allowing rain to flow into the house.

I've been finding the foreclosure / pre foreclosure site but not owners who still own the property. 

You can also check their reviews online at Google, Facebook, or Yelp.

However, this approach may require a compelling story or project to attract contributions.Some people opt for personal loans to cover the down payment, though this can come with high interest rates.Lastly, some private lenders may base your loan amount on the property's as-is value rather than the purchase price.

HI Sherrie, ADU's are generally a great return on investment..I'd double check the DSCR and FHA rates though...A DSCR cash out client was just quoted the high 7%'s to very low 8%'s and FHA have improved tremendously this past week...on purchase quote today FHA rates were in the high 5%'s..check in with @Joseph Chiofalo Good luck!
