We are planning to rent our ADU as an MTR to comply with the law and because that model better fits our business needs.

I work in architectural rendering and 3D visualization, creating realistic images that help investors and developers visualize the potential of their properties before and after a renovation.I have experience in:BIM modeling and AutoCAD.Rendering with Lumion and D5 Render.Interior and exterior visualization for residential and commercial projects.I am interested in connecting with Spanish- and English-speaking investors in the U.S. to collaborate on fix & flip projects, bringing my ability to show how an “ugly” property can be transformed into a “beautiful” and marketable one.I am excited to share ideas and learn from this community.

You might just need to tweak your REI model.   

You can still find deals that meet the 1% rule, and BRRRR works well here with hard money lenders often funding 100% of the purchase and 100% of the rehab (around $10K out of pocket per deal).The key for new investors is surrounding yourself with the right local expertise — an investor-friendly agent who also owns rentals, plus a team of property managers and contractors to keep eyes on the ground.

.- alternate rent models: STR, MTR, rent by room.  

Your plan to use the HELOC to buy, rehab, rent, and refinance (the BRRRR model) makes a lot of sense, and a lot of investors get started this way.

The oxford house model requires that all tenants pay equal share of the rent per week + utilities no matter how many beds are filled so if all 10 beds are not filled then the weekly rent/utilities goes up for the remaining tenants so its super predictable and consistent for the landlord. 

Suggest you get professional assistance the first time, then decide if you can use your 2015 tax return as a model to go it alone with TurboTax in the future.  

I personally know people that have gone, and they all claimed that it changed their business model completely, in a positive way.

I see myself in them: young, dedicated, but lacking role models, something that can be dangerous for a young man.
