I told the tenant that I would need to call this property uninhabitable (since she had screamed at me about how the mold and bacteria from the sewage water can harm herself and her child) and asked her to find herself alternate accommodations.

I am open to suggestions or any other alternatives to make money. 

If you were a private money lender, what would you suggest I do to attract you to my deal?

Alternatively, any other suggestions on how to get the equity out of my primary residence?

What attracts me to this is the freedom and of course the money.

Alternatively, you can also diversify your risk by changing up multi family to corporate or other short term rental strategies that are less expensive and yield great returns. 

You're not going to be able to use the lease to enforce all kinds of arbitrary, petty, often vindictive rules, as we often see here by new or mentally deficient landlords writing here on Bigger Pockets.So for us, the best alternative is to introduce ourselves as the landlords, have a straightforward lease, screen carefully, and avoid signing leases for more than six months or a year.

It may sound attractive, but all real estate investment options are still built on your number in and how you run them.

If the OP has a genuine explainable change of circumstances, he can disclose it to the lender and the lender can either recall the loan, consent or offer some other alternative.
