Most of our properties are 1-4 units with a smattering of commercial as well almost entirely in South and West Sides (no suburbs).I don't really care about the size of the bank but, ideally, we would find a bank that has:- Great customer service- Competitive fees- Highly functional online platform (and services that can help reduce overhead, like remote check deposit)- A willingness to at least entertain lending to an operation like ours (long term financing and potentially some operating lines)Any ideas/intro's would be greatly appreciated!

Im also all ears, and appreciate any advice/constructive criticism, but really just wanted to introduce myself because the email said to do so.

The existing windows have provided functionality for decades and tenants will live with old ones. 

I like to concentrate on the interior items to make the place functional but make a list of all the exterior items that need attention as well.

I always tell my tenants to notify me when there is a plumbing or electrical problem and I tell them not to worry about being blamed because as the owner of the property it is my obligation to make sure that everything is functioning as is expected.Treat your tenants with the respect they deserve and the way you like to be treated.

Codes are minimums for a satisfactorily safe and functionally built home/building.

Loan amounts and rates are a function of property cash flow, your credit score, LTV, loan size, cash reserves. 

The IRR function in Excel is a lot easier than people think.

Once you get a new system put in, see if the company that installs will give you an inspection letter that the system is functioning well.

If it's functional and meets the needs of the building and there is no mandate to replace it from anyone (e.g. local building dept., CMHA, your insurance co., etc.)
