I'd prefer a small business.

In 2015, my sister had a business which was essentially her livelihood.

For example, for a business owner; they have no practical way to 1031 exchange.

@Emily CurtisI am a BP Pro Member with login of my personal email I have been using Stessa for 3.5 years using my business email address for login.

No business succeeded by drilling many holes.

@John Davey Interest on a home equity loan used to purchase or improve rental properties is deductible on Schedule E as a business expense, but not on Schedule A for your primary residence.

I went through it anyway bc she had a good footprint online, I liked the designs, and a couple of ppl at another STR group recommended her (not an excuse, I was super busy and thought I was dealing with a professional).

Several options you can explore to get the down payment capital: Solo401k; HELOC on personal residence or from equity of the SFR; Cash Value Life Insurance Policy; Business Credit; Private Lenders, to name a few.

That lasted a few months, but the REC recently released a new bulletin clarifying the legislation and basically saying that bill was meant to stop all forms of "wholesaling" as a business practice.
