I am looking to expand my business and wondering what marketing tools others have used to grow there portfolios?

Yes, it is in my business name @Christopher Phillips

Quote from @Gian Pazzia: For properties that small, you should budget $450 per property and use software like the one below from a trusted brand that has been in business almost 25 years. 

Check your local and state regulations regarding this business model.  

I no longer qualified for traditional financing because I already own many rental properties and my DTI was high for the bank, so I purchased these in a business entity with a trusted private investor and was able to refi the 1st property/sell the 2nd property to pay back my investor and ultimately keep the better property for zero money down.

To be regarded as a real estate professional, you must perform a substantial amount of real estate business, defined as more than half of your time, and at least 750 hours, spent in real estate trades or businesses. 

This is why I do all my business in OH

Do NOT do business with Deal Machine or their affiliates.

We typically look for areas with great schools in business oriented areas.

Meaning, if you need to do your own pm in order to make an investment work then the investment doesn't work, and you are trying to force it.PM is a job or business, not a required skill for a rental investor.
