But things change, and I doubt they would expect you to live in it forever.

I know of a community bank up here that has done 80% LTV on refi’s for multi-unit properties but again the rate and terms they offer will be vary based on several factors. 

Lots of factors that will impact your #'s. 

Also, sustainability is a factor. 

You and I also know that the most important factor in deal success is the sponsorship group, not the property.

Because most often those are the factors that prevent you from getting a mortgage.  

Key factor is - what is it actually worth to YOU and YOUR DEAL.If you can't get it for the price you require - then pass on it and find another.

Over-financing can be an issue when too much money is borrowed (the interest rate and length of the mortgage are factors).Warren Buffett refers to free cashflow as owner earnings, which is money you can safely take out of the business without jeopardizing the business.

All this to say that HIGH OCCUPANCY at the end of the day is BY FAR the most important factor in this business.

Usually schools and crime... walkability comes in to play in some areas (usually more urban,) but local conveniences certainly can be a factor.
