Really is amazing how many visitors flock to the island for summer vacations. 

I recommend learning the various ways to search and identify good opportunities and once you present that to suitable investors, the capital will come in.Get educated here, learn, and put it to action.

I would need much more information to advise on whether further real estate investing is suitable at this time in your lives. 

If so, having some knowledge yourself on the local market is sometimes a suitable way for investors to narrow down the list of options. 

Should I discuss this with the banks I visit or should I find a financial advisor for that later on?

That's not suitable financing for buy and hold.

You need to make the effort of underwriting & registering the mortgage and tying up your capital is suitably compensated.

Arlington is a great rental market, so you don't need to go far to start your search, though I wouldn't restrict it to Arlington.I'm both a REALTOR and a wholesaler/investor, let me know if I can assist you in finding suitable rental properties.

Funny thing happened around 2003-- by 2006 i was selling- real estate price appreciation was abnormal- Banks started lending money to anyone including non citizens no doc loans- Lower income people moved in my neighborhood in droves- the local mortgage office had a tinted black front window - i am seeing a new strange visitor-- the newly minted chinese millionaire that has illegally sent his money to the usa--- they are bidding with bags of money and overpaying for the real estate--- this is another disgrace of this country not following its own laws.- Pay particular attention to california and ny 

I'm sure I can find suitable replacements for most of the services a management company would offer, especially for a single small multi family.
