Was I supposed to be paying quarterly taxes to the IRS from the time I made a profit in 2018?

What is the difference between hopping on a flight to PDX or DFW?

There are also some IRS publications related to rental properties.

Do you have the IRS code section stating where you can offset 25k of active income or ordinary income with passive losses?

Yes, this is a common course of action among tax deliquent property buyers but I have never been successful for the following reasons:1) You have to research the deed to the property and ensure all owners are identified and sign the quit claim deed.  2) Contact the IRS (or have a real estate lawyer do so) and find out if there are any outstanding federal tax liens on the property.3) Contact the local county and city officials to get a list of all civic liens other than taxes due. 

You don't need to hop on a plane & personally tour every $50,000 house you buy but you'd have to be a madman to buy one without hiring a 3rd party inspector to give it a thorough inspection.Using cash.

@John HeeneyYou want to make sure to go with a provider that will be there for you to no only process the required IRS plan updates but to answer technical questions.

Not expecting it to double in 12 years again, but we are taking a long term view on this investment too.The liens are IRS tax liens from the business they lost around 2012.

We recommend avoiding such a transaction due to IRS risk and a real lack of clarity on the topic from the IRS or the tax courts.IRS rules prohibit any direct or indirect transactions or provision of benefit between a plan and a disqualified party. 

It is something that you should track the details/progress throughout the year.The IRS may require a log of the hours spent in the case of an audit.
