advise on RE purchasing

[Jose Vasquez]

Hello everybody, first of all I want to thank bigger pockets for this website there are so many things to learn especially when you're newer in this area. I am a 60 y/o man, I live in northern Colorado (Greeley) I need advice on how to proceed I currently have a primary home I also have a duplex (both mortgages), I want to improve cash flow and possibly purchase Investment properties, I can either refinance the duplex or take out a HELOC ($150,000 in equity), I can also roll over an IRA with approximately $300,000.

What should I do next? Refinance or HELOC or something else, on duplex? once I get that money and also the roll-over IRA = total approx. $450,000, what is the best use of this money? should I consider STR? or duplex/multiplex? I also need to consider tax implications... Open to referrals to a knowledgeable tax specialist/CPA.

TIA!
