You can get a normal owner occupied home loan to do this. 

A good tax accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant who specializes in business taxation, financial planning and tax planning.I would also recommend looking for a accountant willing to work with you throughout the year.

I bought my first house when I was 24 and now have 5 relatively small properties in Michigan!

I had to live in the property due to the FHA occupancy rules, so I had about an hour and 15 minute commute to work every day.I settled on Tilton (small town in central NH) because the property was right and it cash flowed very well, and was quite cheap (at the time... 240k), I could get the loan to get into the building and own 4 units.

you will not find a cashflowing property at 100% financing whether its with a traditional loan and heloc or whatever the terms. 

Is it hard money loans, angel investors, etc?

.- Collect Tax Certificate to verify Property Taxes are Paid- Get a current statement from the seller to verify the existing balance, if they are delinquent, you can get the bank on the phone to verify the amount to make the loan current.- Review the loan documents, there is most likely a due on sale clause, which is why you won't find a title company to process these for you.

Texas does have specific rules regarding home equity loans and cash-out refinancing (often referred to as "Texas Equity Section 50(a)(6)"), but these don’t prohibit homeowners from using funds for investment properties.

I’d like to put as much down as possible with  conventional loan.

If it is someone you know you can give them a straight return as if its a loan - can provide a lower interest rate to provide upside - it really depends on the lender and what are they concerned with and what is their risk profile.
