I would recommend seeing the eviction through to completion and using it as leverage to recuperate as much from the tenant as possible. 

It really depends on your goals and whether you prefer to use your own cash or leverage financing to grow.I'd be happy to run some numbers for you!

I don't think leveraging what you have equity wise would help.

I'm generally a proponent for alternative lenders if they can provide better leverage or if they are needed due to time constraints.

But it’s clear you’re a smart investor who knows the long-term benefits real estate can bring.I keep reminding myself why I stick with real estate: you can make money every month in four different ways:Cash Flow – Passive income to live on.Appreciation – Long-term property value growth.Depreciation – Tax benefits that reduce your taxable income.Tenants Paying Down the Mortgage – Even if you’re paid off now, this is one of the biggest wealth-building tools for leveraged properties.It sounds like your main struggle is the stress of active management—and trust me, you’re not alone.

Make sure you know the value the ADU will add to the property before building the ADU. 2) the financing on an ADU is typically far worse than for initial investment property acquisition or is often not leveraged by the ADU (HELOC, cash out refi, etc).

From turnkey rentals to syndication - real estate has significant risk and the more leverage you use the more amplified that risk

Avoid over-leveraging your home to minimize risk.

A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant who specializes in real estate taxation, business taxation, financial planning and tax planning.I would also recommend looking for a accountant willing to work with you throughout the year.

As you and @Wayne Brooks both pointed out, could even offer some leverage to myself as the buyer.
