If you end up leveraging your residence so that you can invest the money, be sure that you don't put yourself into a position where you would lose your residence if the investments go bad.You have another choice in your posts. 

My second is not the ideal and best choice but doable with the type of area you work with which is self installation.New hot water tanks are about $400-$900 depending on the need for the client plus any pipe adapters for the tank if needed as well as paste or tape for sealing the utility pipes. the package include instruction about installation which was not bad out of a 5 point scale of difficulties i give it a 2.5 or 3.

I have a lot of time and I am comfortable in the money department so I thought doing something more "productive" would be a better choice to use in my down time over the games.

No choice really since the building is sandwiched between 2 other buildings.

Decide which type of RE investing motivates you the most (BRRRR, Fix and Flip, Multi-family, Commercial, Syndication, etc.) many choices out there find what fits with your personality and have fun with it.

I was hoping someone here could help tell me if I am correct that its a good buy or why I am wrong and its really a bad choice.

Great choice for the older generation. 

My main business plan focus is doing BRRRR on multi-family units then quickly moving up to larger and larger apartment complexes.If you had your choice of any course (aside from getting a real estate license), what would you take?

J&K are also a popular choice for flippers. 

In lieu of appliances and deck repair I said I would drop price to 59,500 (was $62k), their choice.
