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.

If you have access to the MLS this data can be acquired by searching for sold and expired properties in your area over your desired time range.

Higher up = less maintained roads in the winter, and this is a ski house, so access during storms is key. 

Hello Everyone,Looking to find out if anyone has access to a lender either locally or nationally that will do HELOC's on 1-4 unit investment properties?

I am a Realtor and have access to a lot of off market deals and would love to be your eyes, ears and feet on the ground here given the opportunity!

I am not a tax expert and not really trying to answer the question but instead pointing something out that you may not be aware of because you are not from Ca.Due to 1978 Prop 13, the property tax on the unit is based on the accessed value which was the purchase value with only 2% growth. 

Every area is different, site conditions will bury, local access to the materials and delivery or make a difference.

Is there a way landlords can have access to these resources?

Every agent has access to the MLS, not every agent has experience working with investment properties, wholesalers, REO agents, etc.
