I work closely with many buy and hold investors and would be happy to share insights or explore ways we can collaborate. 

I rehab and also buy and hold.

You'll also have to register any such LLC in the state where you buy properties.

Also, you don’t need a business license just to look at properties, but if you buy a bigger property, like a multi-family unit, you might need a certificate of occupancy, depending on the local rules.For business trips, most expenses can be deductible, but if it’s part personal and part business, you can only deduct the business portion.

Im really interested in buying some cashflowing rentals in Ohio, Indiana, Arkansas, maybe the Carolinas.

I would both buy a property to get your feet wet and at the same time make a plan to scale.  

@Polat Caglayan very ambiguosu question, but read the helpful info below to guide your next set of questions:)-------------------------------------------------------------------------------------------Recommend 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?

I'm looking to purchase a single family home as an investment property (buy and hold strategy).

Philly has a ton of opportunity, but since you are new to the area, I would suggest waiting six months before you buy anything there so you can really understand the block construction of the area.

Do you want to be solving tenant issues, buying properties, problems at work, etc.
