@Noah Bacon Investors should be aware that, in many states, an investor can not act as Owner/Builder on a property that is not their primary residence.But as far as what Investors tend to screw up, the list is long and painful: Structural - Awful framing, undersized headers and beams (or none, Lol)Electrical - Don't even get me started......Plumbing - Not as bad as electrical but still....leave it to the Pros.And the main thing that people screw up is, believe it or not, painting.

@Mike Dayfor what it's worth i was skeptical of your numbers too, i think they're overly optimistic and i tend to agree with @Dan H. in the spirited discussion you have been having. 

Tenants signing longer leases tend to break them more often than not.

.#4 Higher Appreciation Potential:Single-family homes tend to appreciate more consistently and at a higher rate than small multifamily properties over time.

I’ve found that by investing in better locations I tend to get better tenants and a larger tenant pool.

Like a trust.LLCs do not open some magical door to more tax deductions.I tend to recommend LLCs where the properties are located, but then those LLCs are owned by a Wyoming multi-member LLC.But if you think that you can skip fixing that loose railing and hide behind an LLC when the tenant is injured, you'll regret it.

People tend to shop with their eyes, so give them something incredible to look at!

My ideal clients tend to not think like residential buyers.

You can generally place a voucher tenant in any property.In order to place a section 8 tenant you will have to pass an initial inspection as well as an annual inspection where they tend to be more strict and have you fix things that you may not have addressed for a market tenant.

You're smart to ask these types of questions so I'm sure you'll avoid making the snap decisions that tend to get many doctors in trouble.
