Owner is motivated to sell and says expenses are $2300/month (includes lease rent 1700+600 in electricity/gas water included in rent).

A person goes to fuel station, pumps 20 gal of gas but only has $ to pay for 5gal, what happens????  

Tenant shall properly use, operate and safeguard Premises, including if applicable, and landscaping, furniture, furnishings and appliances, and all mechanical, electrical, gas and plumbing fixtures, and smoke alarms, and keep them and the Premises clean, sanitary and well ventilated.F.

While i'm happy, and relieved, I don't want to take my foot off-the-gas, and ensure i'm positioning myself for consistent stays.

Moving a gas appliance (range, or furnace) would require a permit.

Go gas or electric if you can.

I was just reading in Docusign and in Mexico, Docusign gas a wisird where you can close everything with digital signatures there ar is a certain procedure but the notary will get in one of the room or conference and be done.

Can I write off all expenses from the trip, such as hotel, meals and travel costs like gas, or airfare?

You could have a few things driving the cost:-Location - if the house is more remote the contractor will have higher costs to get out there (gas, lodging, limited resources) or if you are using a local guy he might be higher because he knows there are fewer competitors -El Nino - the roofers we use are all busy because people are rushing to get work done before the rains hit.  

Currently I have 2 accouts in my name at my current address's I have the property management meter gas & electric which is the main meter for the priority & my own which is my apartment.Ask me how I had 2 accounts at the same address?
