Also, which choice is better for you highly depends on what your real estate goals are and the experience level & skillset of the specific agent.Traditional agent and Redfin Agent could essentially be the same thing in many cases.

Quote from @Matt Wan: Can I purchase a property using a traditional mortgage without being physically present for any part of the process?

For most single-state investors, a local LLC is the practical choice. 

Are you purchasing them at full retail value after they're done or are you the one purchase the shell doing the renovation but they're just doing the leg work ? 

This can be very expensive and is usually the worst choice because you can't justify the cost.2.

@David YoungRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Some will criticize your choices, but understand that their judgment often reflects their own insecurities.

Im looking at purchasing a duplex in middletown, Ohio.

We have worked together for 5 years, and two of your four properties, purchased I believe in 2022, have both renewed their leases and are operating smoothly. 

Basically, two choices on the market:1) All-in-one units, typically used in apartments2) Separate units that are stackable - usually higher quality than #1
