Intangible assets like goodwill or tangible personal property (e.g., equipment) are excluded from 1031 treatment and are taxed separately—goodwill is typically taxed as a capital gain, while equipment may be subject to depreciation recapture taxed as ordinary income.To minimize taxes on the sale of the business, consider strategies such as Opportunity Zone investments, which defer gains until 2026 if proceeds are reinvested in a Qualified Opportunity Fund (QOF), or structuring the sale as an installment agreement to spread taxable income over multiple years.

Living in one unit and renting out the others allows you to deduct 75% of expenses like mortgage interest, property taxes, insurance, and shared repairs as rental expenses, while the remaining 25% applies to personal use.

Personally when buying rentals I tend to buy in neighborhoods that I feel like I wouldn't personally mind living in and when I look for tenants I try to look for people that not only pass my screening but also I personally don't dislike.  

Personally I think this is where a lot of sale lease back programs fail the seller.
