There are a lot of variables on a raw property.  

There's a lot of variables that go into play as far as what may be the best fit for you CRM Wise, but I agree with @Freddy Alban in that "The key factor is the follow-up capabilities, so pick one that excels in that area."

You have the manufacturer parts warranty and then the contractor labor warranty and if contractor was smaller they might not be around anymore when a problem arises. 15,000 sq ft roof depending on variables running about 8 bucks a foot but can go to 12 for a flat roof just varies on time of the year, amount of labor hours to remove current roof, and any product shortages.I would check right away to make sure the roof warranty was transferred and is not null and void.   

The rates on HELOCs are low right now, but they do need to remember that the HELOC is variable.  

It was too many uncontrollable variables and we decided to give up on that.

If it was municipal water, I would bill the tenant back because the cost would be variable based on usage. 

Too many variables to pin down a number.

I know many variables exist, but I am conflicted about whether to build or invest.

But both feature modulating compressor speeds so variable cooling which can save on electrical, again more so in the swing months.As you have heard the positive of ductless systems is that the refrigerant lines are smaller than ductwork so they are great for installation in much older building because there is less intrusion of the structure for installation.

There’s too many variables involved.
