I have self employment income and no w2 employees.

My question is should I sell now ( subject to short term capital gains, self employment taxes) or rent out and sell after the one year hold ( subject to long term capital gains) ?

Perhaps you have a different method of calculating cash flow. 

I've found it to be an excellent method for building a client base.

After the housing crash, my long time tenants moved out and I was moving off to grad school, and I could not sell my house (I was way underwater on the mortgage), so I ended up renting it out.I only recently got above water on that house, and it is not the best investment property, but I'm keeping it for now since it is finally generating a positive cash flow.I've recently come into a lot more money (self-employed), and am now in a position to buy even more properties, but I want to do it right this time.

They will do a credit check and look at the credit score of the applicant(s).Prior to closing they did a verification of employment that took 2 days.

It's great to hear what successful investors have done and their different methods.

What investment strategy would you employ and how easy is the latter to accomplish with a lender?

These include the self-employed and commissioned sales people with excellent income, credit, and an adequate down payment.

I am interested in working with someone familiar with BP's methods and interested in working with someone wanting to acquire as many units as possible.
