If you can find one, that would be my first choice, but I would not use the HELOC for a long-term investment.

Again it depends on the investors choice, me personally am not into D class buy and holds.

q1:If a couple could choose to sign divorce papers before or after the sale of the home is there a better choice? 

It's also beneficial to continually educate yourself on real estate investment strategies, market trends, and financial management to adapt your strategy as you grow your portfolio.

I would only consider this if they can demonstrate they are a professional company with a long history (operating 5+ years would be my standard), and if they are willing to make it financially beneficial to you (higher rent rate, they handle maintenance, etc.).There are a lot of "businesses" that started recently that have no real experience, meaning they've only operated in a strong market.

Your best choice will depend on your goals and risk tolerance.

Make sure to connect with everyone in the community, you will find it beneficial to your goals.

For me, I have not yet finished my research, so I cannot tell you my choice. 

If you go to a factory that builds houses you are buying a building where some of the choices have been made.Good luck!

If you're like me, who used to own 11 turnkey rentals and sold them all, and many accredited investors go through a similar process, then doing a cost segregation may not be the best choice.
