I am willing to share everything I know for the cost of lunch somewhere in West Hartford.

Usually, the "materials, colors and fixtures" that are "in-vogue" will also be mass produced (which also means "cheaper") and sold at your local Home Depot and Lowes. 

The primary residence is a cost center and loses you money, since you shouldn't bank on appreciation.

I am putting 20 % down ( 90K) but I see there is about 27K in fees and closing cost.

You don't think they will want their insurance, which I assume they've been paying out of pocket for many years since the house was build and owners never paid, to cover the cost of a new roof and fix the leak which appears to have been there since the house was built?

Keep in mind that even with such a low LTV, you might not find anyone to lend above the UPB of the note. 

If you are planning on buying it with a smaller down payment, that will also increase your mortgage costs as you are borrowing more and also need mortgage insurance.The price of the home (from the seller's perspective) is based on market value and condition, not on whether or not it matches the 1% rule.   

If you have the checkbook and stomach for renovations, there are some serious value add opportunities on older properties as well.If you're just looking for a low price point, that is a different conversation. 

However if you want to generate more cash flow putting 15% down will help you because not only is it a lower montly payment but when you hit 20% equity they will remove your PMI.If you put down 5% I would stronly encourage you living in the Airbnb if possible and renting out the home so you can generate even more incomeIf you look at it like this it'll helpMonthly payment < Potential income + current rentIf you can move and reduce your cost of living that is always great at the bare minimum they should equal each other in my opinion because at least you'll have equity if the market you are choosing is a strong equity market.

Sub-par work, cost over-runs, undisclosed delays and work beyond their expertise?
