@Jerry Velezif a property is owned outright with no mortgages, debts or liens on it, then it can (potentially) be purchased on seller financing. 

So, you can do a land contract for 12 months, which should allow lender to credit you full value of the land vs the purchase price, but the loan will pay off the land contract, so the lender maintains first lien position.Can't help you with the rest of your question, but you should be able to search for "CPA" here on BP to find experts to reach out to.

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

Purchase price: $275,000 Cash invested: $294,000 Sale price: $355,000 Seller was behind on pay HOA payments and in risk for losing the property.

Step 1: Get preapproved for an FHA loan for the purchase price you are looking for.Step 2: Connect with builders until you find a few that will finance the construction of your home. 

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.

Are you purchasing a fix and flip property and looking for a hard money loan? 

Quote from @Jaren Taylor: Quote from @Stuart Udis: Depending on the transaction sizes you are pursuing, raising money to purchase property without debt requires either an incredible network of relationships or devoting a lot of time and effort to raising money.

These are great questions and a great idea to do some due diligence before the purchase.
