We purchased the house about 3 months ago and are owner financing it.

I'm looking to purchase an investment property in Allentown PA.

I have a followup question - I will realize a lot of capital gain from this home in Idaho, so I think unless I purchase a new primary residence I will have to pay that capital gains tax. 

Quote from @Cody Lewis: My wife and I recently purchased our first STR.

I'd say if you are looking for commercial real estate wherein the purchase bought the property in a corporation then PS is not the best place for lead generation and skip tracing. 

Being able to purchase a property with only 5% down means you can leverage your money way more effectively.

I've got about $525K in equity in the property, but lenders have told me that I cannot get a HELOC to access that equity for additional purchases because the duplex was financed as an investment - they have said TX law dictates that HELOC can only be used on primary residences.

These are things at the high level I want to be looking at for all my real estate purchases. 

To defer all tax you must purchase in total at least as much as your net sale.

Purchase price: $325,000 Cash invested: $50,000 This time I acquired a property that needed little to no work.
