Meanwhile our property taxes doubling and property insurance etc.

This is a pretty vague question, it all depends on purchase price, loan amount, interest rate, taxes, power, water, sewer, cap ex, vacancy, maintenance, rent price.

You will be responsible for property taxes and insurance which will likely be higher than what the current owner is paying because it’s never not been the case for me.

One of the main issues is how does the tax part of it work.

Capital Gains tax is triggered upon transfer of deed and I have to pay. 2.

However I’m not afraid to try or ask for helpSome advise I did receive is Copy of contract or purchase agreementLast 2 years schedule E or tax returns from the current owner regarding the subject propertyCopy of current leases in place for the subject propertybut can I ask for that now?

Working on large-scale data is great b/c sometimes it's all about how many owners you approach daily; the issue with over-the-top details is also getting lost in targeting specific owners and situations, aka focusers/tax liens, etc.

What you want to focus on is rental rate, taxes (income & property), as well as purchasing power in those communities. 

This particular property has been vacant for 10 years, the owner is behind on taxes on the home as well.

Mainly so I can elect to be taxed as an s corp and reduce some of my SE taxes.
