I have had the same portfolio pretty much for the past 8 years and looking to grow using my Helocs.

There certainly are variances, but if you look at a 5-10 year snapshot of most portfolios, you will see the overhead usually ranges from 45%-55% when you have actual numbers for vacancy, maintenance, and capex.

My portfolio is split about 50/50 between real estate and paper assets.

There were three that struck my eye based on their type of portfolio being offered . 

Concentrate on initiating your wealth building and real estate portfolio in that proximity.

Would like to build portfolio.  

Don't take on turnaround or upside projects until your portfolio generates consistent income and your financial position has some good room for error

You will not get the tax break, but building a Roth portfolio early in your career can have a huge impact on the amount of after-tax money you will be able to draw from your retirement plan when you reach retirement age.You will likely change jobs somewhere down the line. 

You will need to find a local portfolio lender that will have different underwriting guidelines.

Will eventually refinance through a portfolio lender with other properties.
