If you have access to those kinds of private funds (through friends and family?)

CF is certainly more accessible, but it's almost like picking stocks or angel investing in startups... if you can, you might want to spread the $ across a few deals, doing less on each. 

Bernie Sanders wants a 25% “house flipping” tax levied against investors who sell a property at a profit within five years of purchase.He also wants a 2 percent “empty homes tax” on the property value of vacant homes in order to discourage real estate investment.From Bernie's Website"When Bernie is president, he will:Create an office within the Department of Housing and Urban Development to coordinate and work with states and municipalities to strengthen rent control and tenant protections, implement fair and inclusive zoning ordinances, streamline review processes and direct funding where these changes are made.This office will convene key leaders, academics, experts, local officials, renters, tenants, and homeowners to create and implement these necessary solutions.Preempt laws that prevent inclusionary zoning for luxury developments.End exclusionary and restrictive zoning ordinances and replace them with zoning that encourages racial, economic, and disability integration that makes housing more affordable.Require that recipients of federal funding from the Department of Transportation and the Department of Housing and Urban Development make these important zoning reforms.Provide funding to states that preempt local exclusionary zoning ordinances to make housing more equitable, accessible and affordable for all.Make federal funding contingent on creating livable communities.Encourage zoning and development that promotes integration and access to public transportation to reduce commuting time, congestion and long car commutes.Prioritize projects that reduce greenhouse gas emissions, create walkable and livable communities, and reduce urban sprawl.Encourage zoning and development designed to expand and maximize the number of units fully accessible to people with disabilities.Place a 25 percent House Flipping tax on speculators who sell a non-owner-occupied property, if sold for more than it was purchased within 5 years of purchase.Impose a 2 percent Empty Homes tax on the property value of vacant, owned homes to bring more units into the market and curb the use of housing as speculative investment.Encourage “circuit breakers” on property taxes to protect homeowners in gentrifying neighborhoods from being priced out of their own homes as their property values rise.READ MORE: https://berniesanders.com/issues/housing-all/From my point of view, anything that impedes or obstructs REI's cash flow is a bad thing.

Which cash access option is the best or would you recommend?

You can try the RPA Online Access system, but it is more costly and may (not sure because I've not used RPA) require a company to access.

I would clear up the communication issue and plan on having a representative there to grant access to the repair person.  

Being in proximity of a highway can mean easy access to it and it can definitely be a selling point.

Knowing the market, inside track on big players, gaining access to the realtor community for networking and knowledge.

The duplex would also be close enough to the road to access city water and sewage, where as the rest of the property is not close enough to access them. 

Great location, easy access to all shopping and services, and a quick commute to Ithaca, Binghamton or Syracust.
