@Toby Ng welcome to Bigger Pockets!

In many regions we don't have NG and oil vs. propane is pretty much a wash.

NG will pay for a portion to all your school as well.

It has good insulation and brand new dual pane/argon filled windows but with this past winter the NG bill was higher than $100/mo for ~1200sqft.

@Lu Ng Selling Price = 520,000Approx.

If its in the crawl space theres a good chance its the beam supporting the center of the house.You could jack up the existis,ng beam and add new supports.If you send me a pic I'd have a better idea.

They pay month to month but may be moving out shortly.Don't believe NG will be available for a while but would consider it when it became available.Thanks for your input.

Thanks for the info on NG prices.

I have a formula on each line that adds up all the categories on that line, compares it to the receipt total on that line, and prints "ok" if it adds up, or "ng" if it doesn't - this provides a check on my work of splitting it up.  

@Kendric Ng I started investing from the bay area and move out of california this year.
