Buildings of this age can have costly insurance as insurance companies know unless everything has been replaced the failure rate for things increases along with frequency of increase of claims.What is the turnover rate for the apartment and what vacancy is the seller reporting??

I would expect the frequency of sales (turnover?)

Curious as to what your experience has been with respect to frequency and lenght of campaign.  

And for many who have cash they get hooked to the passive nature of the business and to the returns that over time will usually out perform rental properties.Once folks have been through the rental cycle and realize how tough it is to be a landlord they start looking at lending its a natural progression.. of course many have a combination of both.. but I have seen it happen with great frequencies over the years.. my clients selling off rentals to put into notes.

But a new market is a new world and you need to mitigate risk by pulsing experts, agents, investors, business owners, renters in an area to vet your analysis as much as possible, and use online resources to check crime rates, school system strength, foreclosure  frequency etc.  

My best guess is high frequency traders (a.k.a. computers) making algorithmic trades based on current positions, not the fundamentals of the companies or the economy. 

I don’t have to worry about rumors affecting stock prices or high-frequency computers making automated trades that affect a sell-off.

Reducing claims frequency will help with the stability of your rates and help secure a wider variety of coverage options for your property.2.

And that starts with consumer complaints.. and based on the less than knowledgeable folks that post on BP that really have NO business getting into the middle of what is very serious business for a seller I can see this happening with more frequency. for whatever reason and I guess because of the internet people want to get rich in RE with no money and no credit.

So you refine, rinse and repeat and all of a sudden the leads come in with more frequency and at lower cost.
