In my opinion, the modem is less important than the router.It's also important to have dual band router. 

You have to narrow it down. 

I can help you out as I know the area very well, but need a bit more specific info and a narrower geographic location. 

Narrow down top 1-2 markets based on cash flow, ease of entry, and appreciation potential.Good luck!

Once you have your financing & budget squared away, you can narrow down the areas you want to focus on & ultimately purchase in.If you need a few referrals, let me know.

For recent purchases: less than 3 years, you probably have to grow with them and think about how can you maximize returns: maybe ADUs, or Coin-laundry or e-pay, renting space on the property for storage, air b and b or mid term rentals, splitting the lots, Tic sales etc... or value add to increase appreciation faster!! 

They are in B and C class areas.

Have you started looking at specific markets yet, or are you still narrowing down your options?

Thank you so much for your response and your helpful tip, I will definitely narrow down my search for turnkey property.

It helps to narrow the list of good options.
