We've only been here about 3 months, liking it so far but I feel like it was 103 degrees last month and now I'm freezing :)

The values vary widely in sometimes just a few blocks.

On an actual owner financed sale, generally varies from 4-10%.

Keeping in mind this can vary widely: I would say seller financed interest rates would generally be above standard bank rates yet lower than hard money.That is the question asked.

Here is what I was taught a good comp should be:- 6 months of sales-  +/-200 sqft of subject property (1,000 - 1,400 in this case)- 0.5 miles from the subject property- same ba/br or close to it and adjust- do not cross major boundaries such as a different city, freeway, major road, etc. because local markets vary significantlyI'm not happy with this person using 12 months of sales data, but okay I get it.  

The good thing about having a few months before you begin is that to a degree, you can get these systems in place now.

In some areas it can even vary by county.

The way it works, which varies from lender to lender, is you can refinance all your properties into into a single loan, with a refinance up to 75% of Fair Market Value.

The prices vary from $80k-$175k (ideal purchase price so my numbers work). 

Moreover, I am currently earning my MBA degree from Western Governors University while working full-time as an IT analyst.
