I like your plan of buy/rehab/hold and flipping to supplement.

They are building a team together with specializing in the hospitality industry.

Hey BP community,I am looking for a property/building inspector that specializes in multi-family property to help me inspect a property in Jacksonville FL area.

Scott The Book on Flipping Houses, The Book on Estimating ReHab Costs http://www.biggerpockets.com/flippingbookYou might consider Niche or Specialized Housing like student housing.

I best advise you to consult this topic with an accountant who specializes in REI.

you might want to reach out to @crystal Nixon she specializes in real estate and is very affordable.

Many were start up companies in that specific industry, since the property was specialized, and they didn't even have revenues.

Obviously they need to create a special assessment situation.  

There are some guys here on BP that have information on all the subjects that you are asking about and special areas here on BP that talk about what you are asking, check out the education links.  

I live just west of Portland, and I'm looking to get into REI a little more to supplement my retirement as I'm self-employed (General Contractor) and don't have much of a traditional 401k, etc.I started out buying a duplex as my first house back in 2005, which I lived in one side for 7 years and rented out the other.
