Subject too you can get in low cost or free but the risks associated come with the need for money, silent seconds can ruin your personal life and make refinances possibly impossible or can sink the investment throughout or after liquidation.

I fell in love with the software and support, it was too much of a learning curve on my end, had one person (an architecture graduate) do two weeks to customize the whole software, then tried it with several subs, etc, after two months, reality starts to sink in, all operators were grumpy, the subs wanted to just submit the bid and be done with it, it is harder to adjust our bids to clients on the last minute.

We never used the disposal in the sink, it rusted solid and I had to replace it because it would back up with water when the dishwasher would run.  

Just do not sink so much of your liquid reserves into a property use the banks money!

Where is the sink?  

As far as humidity, could just put a dehumidifier with a pump going to a drain/sink.

The cleaner he sent used some type of cleaning solution that stained my bathroom tile and sink countertops.

I am in over my head and it's sink or swim.

I supply toilet paper, paper towels, liquid hand soap at all sinks, dishdetergent, dishwasher pods, one new dishwashing sponge, spray oil, salt & pepper (I buy the plastic disposable ones for picnics so they can't be refilled) and a few other spices, trash bags, some cleaning supplies such as Simple Green and microfiber cloths, coffee filters, plastic wrap, ziploc baggies, laundry detergent, and dryer sheets.Guests are asked to bring their own shampoo, conditioner, personal soap for showers, sugar, creamer and coffee. 

We are considering adding a roll under each sink to eliminate this request/complaint but thought it was odd after years of doing the same thing why we all the sudden had people complaining about only having one full roll to start?
