The problem arises in all this speculations of a market crash lately, as well as the fact that the only way I can aquire this house(because of me moving to another state ) with 20% down.

@Jeff Cua I added a washer/dryer hookup in a garage/common area on a duplex a few years ago.To make a long story short, rents have been stagnant despite my opinion on increased value- at what I feel was a substantial cost…and I didn’t go through subfloors or make the living areas inhabitable during the install, nor have to repair it on the back end.Only you know your situation, local market, etc…based on my experience I would not do it again.Best of luck to you.

Common fees will include a set-up fee, leasing fee for each turnover or a lease renewal fee, marking up maintenance, retaining late fees, and more.

If the need arises I would just request the extension while under contract rather than with the original offer.

Very common tactic for the Fake lenders out there who do nothing but collect up front money and are just a scam / criminal enterprise. 

Most of the issues that could come up on an FHA appraisal are pretty common sense; mainly safety hazards and structural issues.

Regarding the water dispenser, a common reason for them to not work is the line gets frozen.

The only common area will be a retention pond that is required by the state.

I am responsible for water, heat (gas or oil), common area electricity. 

You touched on alot of points and have some common ideas that most people have when they are starting off.
