As one who personally had a medium sized HML company going into 2007 2008 with 600 loans on my books and by 2010 went through a massive re value melt down all of us in that business got hammered for us we started in 2001 and by 2010 had to basically shut down let go 90% of staff and spent 3 to 4 years hemorrhaging our net worth's to make sure our banks got paid ( which to my personal financial situation was devastating) Most of my peers went out of business completely ( BK) I did not but by 2011 I was basically starting over.

or in the 700's because most people think they have perfect credit.You also have to know occupancy type like primary, vacation, investment, how many units, LTV/CLTV, Term, Fixed or Variable, Prepay or No prepay, Loan size etc.

I would use all 3 plus look at properties currently available for rent that are similar to what you are trying to comp (3 bedrooms/2 baths; similar condition; size; etc). 

It is a 6 bedroom and while I see a couple of sales in that 1.6 to 1.8 for 5 or 6 bedroom in that size, that seems to be few and far between.  

So as an example, if the hose sells for 90% of market value then it is doubtful you will get an added 20% on the table with your discount.

The point being: it can be just about any size you want.  

But most pricing is a function of recent comps, adjusted for the subject property by size, condition of systems, and aesthetic qualities. 

You can also just accept certain kinds of pets, breeds, or sizes as a third option.

This question is definitely very location dependent - licensing across state-lines is a tricky thing to navigate so depending on the size of the lender they may operate in one metropolis or all over the country.

If my husband and I were to start over again we would buy higher quality assets and not be focused on immediate cash flow and unit count like we were when we started this after exiting a fairly decent sized small business.
