My other issue I think of when it comes to that is I'm in the process of switching everyone over to non smoking. 

this is where the deals are .Ones that can bite you though are higher end homes where the previous owner strips them takes every cabinet every door every light fixture basically deconstructs the inside of the houseAnd this is how rental property will look over time in many C D markets just beat to holly heck.It's really surprising (when you first start out) how people can abuse a house and what they will actually live in....It's usually either substance abuse or just a bit nuts....or the worst is when it's both.....We should get all the veteran investors on here together and write a book. 

These can be further broken down into lender closing costs and third party closing costs.Thelender closing costs can include underwriting fee, processing fee, funding fee, origination fee, credit report fee, and tax service fee among others.

The closing attorney or Title company may be the determiner for an answer and usually at this point in the process as an agent I'd defer to them.As an investor, I think I'd want all this squared away before closing so maybe check with the attorney/closing company.

Specifically, I'm curious about the cost and process involved.I'm considering upgrading to a 400-amp service, which I believe could be divided into two 125-amp panels, one 100-amp panel, and one 50-amp panel or some other combination.

It’s a smoother process all around

In addition, somebody else is paying off your mortgage and the property can be a good tax write-off (consult with a professional).

While this is the most expensive option, it minimizes the risk of costly mistakes and ensures you’re getting tailored advice.If you’re confident in handling the process, the DIY approach can save you money.

Quote from @Sarah Albert: As discussed in my book, it's best to address these situations before they happen, because they will happen.My lease has an early termination clause that explains the process and penalty.

You want to delegate all the mundane tasks to others and focus on doing tasks that only you can do.While you are calculating the costs of all the raw materials, you also have to calculate your salary into the total cost of writing your own handwritten letters.
