It is very algorithmic-ly dictated based on and numbers and percentages. 

@Dave AllenRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

Other comments on this thread are great, as someone who can speak from experience(even in this local) don't let a girlfriend dictate how you invest, ever.

I would go off of comparable cap rates when dictating the sales price.

Some investors prefer to start saving for these ASAP, while others plan to deal with them when they happen.The unknown is Maintenance costs, which are often dictated by how "hard" a tenant lives in a property.

What is advantageous is someone that is good at underwriting and unbiased (only analyzes the deal based on the underwriting without other emotions).Note i have a fair amount of experience and plan to place a competitive offer tomorrow that the underwriting dictates not placing a competitive offer.  

Me I would convert it to gas but it is the area that dictates it.

I suspect the guests via their reviews will dictate what constitutes a bedroom.
