Saw ad for Replace Your Mortgage Its done with a heloc, supposedly pay off in 5 to 7 years.

Adding to that, unless it's a cash sale, chances drop even further.If seller is selling above market, and you are a cash buyer, why not just bypass that process altogether and show up at the courthouse steps and bid for it?

Post an ad on Craigslist or something, it's not that hard to measure out and paint lines, you could even tell you're manager you'll give him $150 to do it if he wants the extra money. 

Somethings not adding up.  

They are better off building next to the house or adding on to it if they don't want to demo it.

My boyfriend and I bought a house with a walkout basement (with a bedroom and bathroom), we added a kitchenette, and now we rent out the basement area while living on the main floor.

Simply put, you're way too big of an expense when they sell (even for reduced commission, as over many deals it adds up) and they would also get the added savings when they purchase either in the form of price discounts or getting the commission.

A realtor insisted she give me a CMA and estimated I added $10k in value vs the old carpet from a pic I showed her.

I added this into my replacement reserve at 2k a month included in my numbers.The financing is as follows:10 year fixed (2 year option interest only)4.87%  interest only would be 119,280/year . principal+ interest 154,000.Im thinking it is a decent deal based on either option as far as payments go.

She qualified for the 211K, but 245K was outside her comfort zone and went over her allowable DTI (debt to income ratio), but adding $750 per month in potential income to the equation made the 245K property doable.
