I purchase my personal investments to maximize their equity and hold long term.

Private money and personal funds.

@Marc Zak Using an LLC for each property provides strong liability protection by isolating risks to individual assets, with income and expenses flowing through to your personal taxes on Schedule E.

I personally have success in doing flips with my partner here in Ohio.Lakewood and Edgewater are gentrifying neighborhoods in Cleveland.

Figure out which best fits you and your personality and take it from there.  

The question is, what is the intention  of the owner, not what would a reasonable person think is the intention of the owner.

An LLC shields personal assets from business liabilities, while S-Corp taxation allows you to reduce self-employment taxes by taking a reasonable salary and distributing remaining profits as distributions, which aren’t subject to payroll taxes.

A new person moves in and she says the upstairs neighbors are creating a ton of noise.

For example, at the start, do you confirm if all persons in the house are aware of your presence, and do you ask if it is OK for you to open bedroom, bathroom and closet doors?

Personally, I find BTRs to be more predictable with fewer ongoing maintenance issues, and they tend to attract high-quality tenants.
