When you have a clear definition of the tenant base, you gain clarity on which strategies to pursue and can provide a better product to the market, which tends to improve one's odds of success. 

. - I think the problematic part of the argument that government should not allow anyone to build in those areas is that it is too broad of a blanket policy and if the same principle is applied equally to other areas of the state and country, there will be many places that you will want to apply those restrictions to.  

People twist off every day and living next to someone who is so tightly wound only increases your odds of being one of those hit by shrapnel when it happens.

I'm sure it's a good way to find properties since others seem to have success with it but seems odd to me.

In looking at data from PropertyRadar, I can see that most that you will spend time researching will never be sold - which means odds are your "favorites" are probably the owners favorite as well, and they'll work something out to not lose too much of their equity :) 

Those are always odd buildings to have to rent back out.

When you are buying as an investor, only FNMA has a deed restriction on the buy side that prevents you selling for more than 120% of the purchase price for 90 daysWhen you go to sell,  if your buyer is looking to obtain an FHA loan, the contract may not be executed for 90 days from the date the deed is recorded. 

Some are not due to HOA reserves and restrictions.  

However, from the builder's experience, he notes that there are still a lot of restrictions on building through modular construction, specifically in cities and large urban areas.

So here it goes...Does anyone (especially the landlords in the colder states such as Colorado) have a clause in their lease that restricts tenants from using ice melts.
