I love that you have specific goals for 2025 - I believe if we think it, write it, say it, and share it our goals are 10x more likely to come to fruition.Are you able to do option 2 and just house hack a 2-4 unit building and use a renovation loan which allows you to put down 3.5-5%I highly suggest getting to some local chicago meetup groups (we have an in person one on the 17th)...here is BPs list: https://www.biggerpockets.com/forums/521-real-estate-events-...I also have a full list of the chicago meetups that I can share with you too if that'd be helpful.

I assume something like this is more than you want to tackle for a 1st quadplex (https://www.realtor.com/realestateandhomes-detail/241-W-King...), but what about this SF for a BRRR (https://www.realtor.com/realestateandhomes-detail/2101-Arapa...)? 

Oh wow, absolutely love all of these tips and details!

Are there any specific clauses I should include in a room-by-room lease for a shared living space?

I’ve never had this specific issue but mistakes like this are pretty common. 

But for many people, it is one of a number of sources of deal flow, to add to MLS listings, wholesalers, direct owner outreach, auction, etc.Assuming you are specifically talking about sheriff auctions, just make sure you familiarize yourself with the general procedures for the auction.  

That said, I highly recommend speaking with a local professional in the DFW area to get insights tailored to your specific goals.

I’ll add a few more details and answer some questions.

We absolutely love it and are very interested in buying a multifamily investment property in the area specifically a duplex.
