@Douglas Montgomery, I couldn't get the link to load, but if you want to list out the numbers below.Income - Expense = NOIExpenses must include:maintenance & supplies taxesinsuranceproperty managementcap-ex reserveslawn caretrash serviceutilities (if owner pays)snow removal (if required)internet (if provided)security system (if provided) advertisingThen subtract debt service from NOI to calculate Cash Flow.Also, NOI / Total Capital Invested (purchase price + rehab + closing costs + holding costs) = CAP Rate

This brings me to my second question and first tip.Tip#1: While no one can argue that books are a great resource, if you're like me and are diligently managing you budget, the internet has more information than you will ever be able absorb, extort it for everything it's worth.

I don’t think anyone is going to open up their tax returns on the internet, but.....Average numbers I would say Cable/Internet: $175Electric: $200Water: $0 it’s well water (which has pumps and filters that can break any time) Propane: $300 per year Maintenance: good luck guesstimating this one Need more details to get you close to what you seek but @Avery Carl has all of your answers. 

So it's better to leave them dormant for a few years, not to close them.I'm not a lawyer, so take this like any other free advice from the internet.

The internet is an amazing directory for groups and professional meet-ups.

I know which professionals I'll need (realtors/agents, mortgage brokers/bankers/lenders, inspector, attorney/escrow/title, contractors, accountant, management company), but I haven't the faintest idea on how to find the right people beyond endless internet searches and screening, or hoping to find the right professionals on BP in the specific area I want to invest in.

You are joining quite possibly the greatest community of helpful people the internet has ever known.

Don't expect strangers on the internet to serve up everything you need for you. 

The internet is your friend for competitive loans.

Not built based on unfounded promises of "future deals" and phantom internet deals.
