At least in the Sedona area, 99% of buyers are fully invested in seeing and buying homes, and 99% of sellers are fine with buyer foot traffic through their homes.

It is possible to fit in a tub provided that I increase the square footage of the bathroom.

They do not do many, maybe one and half a year or so, but the ones they do sell go for an enormous premium on a per square foot basis.

These numbers do not make sense so trying to use them will just confuse the issue for instance, there is a property diagonally across the street with a "zestimate" of 42,100 (I only wish) , while my 3 bedroom 1 bath with central air in great shape with more square feet on the same side of the street one block away is estimated at 24,900.

There is about a foot of space between the driveway and their house and about 3 feet between our house and the driveway.

Take advantage of the free training available here to get off on the right foot.

If you a comfortable enough to travel between them on foot at anytime of the day then go for it.

For the markets I determine are "green light" markets, I will then start a dual parallel-track process of checking investment opportunities to see if the numbers work (generally speaking) and contacting and interviewing property managers to get their take on the market and begin building out a potential team of local "foot soldiers".The mind dump of metrics I came up with for my analysis so far are (in no particular order):Recent Population growth (2010-2013)Median gross monthly rent (2013)Median gross monthly rent 3-year change (2010-2013)Vacancy rate (2013)3-Year change in vacancy rate (through 2013)Rent as % of income (i.e. median monthly gross rent as a fraction of median household income)3-Year change of rent as % of income% of households that are renters3-Year change in % of households that are rentersMedian price for all SFHs (December 2014)3-Year change in median price for all SFHs (through December 2014)Median price for all 3BR units (December 2014)3-Year change in median price for all 3BR units (through December 2014)Median price for all 2BR units (December 2014)3-Year change in median price for all 2BR units (through December 2014)Median gross annual rent (i.e. monthly gross rent * 12) / Median price for all homes - I know I am kinda mixing apples and oranges here, but it's the closest I can get using available objective dataUnemployment rate3-Year change in unemployment rateGDP growth (time period depends on data available)Job growth (time period depends on data available)Household income growth (time period depends on data available)Proximity to major international airport (i.e. how easy will it be for me to get there?)

If you improve the property and add square footage, you really need to know how it will change the assessment.

For example, you can't just use a $125/square foot rule of thumb, if your particular site and planned design will require more fire walls than some other design, and actually end up costing you $145/foot.
