However, the statement valuing any Property in US is misleading.Rental Properties are valued based on Income while investor returns are measured with either Income or financial modeling tools such as Net Present Value (NPV), and or Internal Rate of Return (IRR).You need to define the intended purpose of the valuation, limitations that applies to your data modeling.The valuation, number crunching is a tip of the iceberg and there have been so many demographic, judgmental factors that significantly influence valuation.

Purchase of lot: i saw one on zillow for $300k 4. hardscape/ landscape : $50k ball park total so far: $1.150 contingency (aka emergency: $50k ) Total : $1.2 million for a custom home at 3,500 living space (you could design the home so that after the fact; you convert a wing of the home (1,000 sq ft) to the ADU. the home would be worth about $1.3 + (equity of about $100k + ) **** If you go the other route: build home at 2,500 sq ft + ADU at 1,000 sq ft you will end up with the same total build out: $1.150 and the value: estimate: about $950k to $1 million + ADU VALUE or about $150k : total value: $1.150 (break even). 

Did some repairs to the deck and steps, cut back some tree limbs and landscaped and cleaned up the parking area.

I am operating in a market with a very heterogenous real estate landscape in a relatively small county, so comparable sales data from Zillow, Realtor, etc is a little finnicky. 

The multifamily I am looking to purchase would be a total remodel new kitchens, new bathrooms, new floors, fresh paint inside and out, reroof, new ac, brand new landscaping, new fence, and maybe new windows. 2921 Bentley St, Sarasota, Fl 34239 sold for $450,000 ($283 a sqft).

The biggest metric that makes me think that real-estate is not going to boom is that we are experiencing a net outflow in migration, and real estate is a demographically driven market segment. 

You will need to find your monthly debt cost, along with all expenses associated with the property (utilities, landscaping, etc). 

There are a lot of markets that cash flow well, however, I recommend focusing not only on short term cash flow but the longer term economic and demographic trends of a market.

Added 1.5 bathrooms, some landscaping and added an outdoor deck for outdoor living, pressure washed the home and painted the front door to provide a pop of color.

Demographically, NYC and surrounding sprawl in overwhelmingly liberal; the entire rest of the state, except for a few cities, is pretty conservative.
