The training from Note School gave me the confidence to buy a house in a rougher area of Milwaukee with little notice and close quickly.

I can appreciate that advise but being a Realtor and and My Dad being an master electrician (with a much broader knowledge base that goes more into being a GC without a license - and no we won't use him as an unlicensed GC) I feel pretty confident that we can do our first flip and be successful.

While this is the most expensive option, it minimizes the risk of costly mistakes and ensures you’re getting tailored advice.If you’re confident in handling the process, the DIY approach can save you money.

Time is critical, especially in competitive markets.Clear Offer Terms - Present a firm offer with terms that make the seller feel confident that you can close fast, with minimal contingencies or proof of funds.Due Diligence Preparation - Have your financing lined up and know your repair/rehab costs in advance so you can move quickly without second-guessing.

I had a few contracts that I was going to use ,however , I agree with you , I'm not to confident in them. 

I’m very confident you only have to provide tenants 30 notice of change of rent terms as long as you aren’t changing rent price above 10%.2.

One attorney said it is a must, whereas other said confidently that it is completely unnecessary.

It will depend on what your goals are, but if you'd like to scale fast, you could leverage the $100k cash to buy 2 or 3 duplexes in lower priced markets that have higher rent/price ratios.You could use these properties to learn the ins-outs of OOS investing and use these to build your network and confidence in the market.

For example:Task             Estimate        % Certainty        Low        HighDemo              $5,000           90%                    $4,500    $5,500Construction   $10,000          80%                    $8,000    $12,000Plumbing         $8,000           75%                    $6,000    $10,000Finish Work    $10,000           90%                    $9,000    $11,000------------------------------------------------------------------------------TOTAL             $33,000                                    $27,500  $38,500So, if the estimate of $33k looks good and the high estimate of $38,500 is still "ok", I feel confident because its unlikely that EVERY item will be that far off.

Plenty of pics and having a virtual tour for potential guest to instill a sense of confidence in the property.
