If you feel ambitious, you could try a BRRR strategy adding additional equity to the subject home and then taking equity out of it to pay off either the HELOC or if you decided to the refinance the primary residence. 

The ADU cannot be superior to the primary residence.

@Bobby Short Depending on the equity you have on your primary residence you might be able to find a lender to finance the property in CR with your primary residence as collateral.

I spent 5 years buying 5 primaries and 5 rentals.

Quote from @Guillermo Perez: Can someone please let me know if this is ok for my first BRRRR.I got a $200k HELOC on my primary residence to help fund my first BRRRR.

Example - borrower uses loan to purchase a home in a B or C grade neighborhood for 380k, spends 50k rehabbing primary home, uses 200k to put an ADU in the back, appraisal comes back at 925k. 

When it comes to real estate, here's a general list of eligible assets and their depreciable lifespans that you should know: Residential Rental Property = 27.5 yearsThis includes any building or structure where 80% or more of its gross rental income is from residential units.That means:- Apartment buildings- Single-family rental homes- Duplexes, triplexes, and quadplexes- Mobile homes (used for residential rental)- Any kind of residential lodging facility where the primary purpose is long-term rentalCommercial Property = 39 yearsThis includes non-residential properties like:-Office buildings-Retail stores and shopping centers-Warehouses-Industrial complexes-Hotels and motels that do not qualify as residential rental propertyLand Improvements = 15 yearsThese include sidewalks, roads, fencing, some landscaping, and parking lots that are separate from the building.Personal Property = 5 or 7 yearsPersonal property used in a rental activity usually has a 5 or 7-year life.This includes most furniture, appliances, carpeting and various machinery.Qualified Improvement Property (QIP) = 15 yearsGenerally, this includes any improvements made to the interior of a non-residential building after the building was placed in service, excluding elevators, enlargements, and the internal structural framework.Computers and Related Peripheral Equipment = 5 yearsVehicles = 5 yearsNote that the land itself is not depreciable.

The best way to connect and learn is to be in rooms where it's going down.In terms of captial your best bet is to focus on a primary income that cash flow sufficiently, saving as much as you can and doing something real estate related so you can get familiar with the industry.

Second, Texas also allows Texas homeowners to do cash-out refinance their primary residence.

I don't know your living situation but if your paying x,xxx for rent or a mortgage and instead by living in one side and renting out the other you will be paying y,yyy instead and y is less then x that's great, especially if you can rent out your primary residence and make income there too.
