Intent is one of the biggest ones, frequency is another. 

Just run the numbers and make sure things make sense.

The good ones can really point to the buyer tendencies and what design attributes buyers respond best to.

To answer your question about the market, well it's all over the place!

That said, I wouldn't let projecting rates factor into my decision as much as whether or not you want to pull the extra $$ out.

@Rosette PooleRecommend 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?

As for the situation, what are you trying to optimize for?
