Congrats on finishing up the rehab, as others have mentioned, make sure to document your work.Keep the invoices handy.

Real estate investing has been a passion of mine for time with my mother also having invested early on where I likely have gotten the love and desire to follow similar foot steps.I have taken last 6 months to educate myself and currently own a single family home as primary residence and would like to expand to multi family properties (2-4 units) for additional stream of income, not to mention potential tax benefits for long-term investing.Based on current living situation, I have a fair amount of equity established in my primary residency along with having enough cash to either pay off house completely or use towards investing in a multi family property.Given that I'm the sole source of income for our household with my wife being the home maker for our two kids under 2, trying to weigh out risks with getting started now or perhaps waiting. 

Watched this one and kept waiting for the point you mentioned.  

This travel expense is not a business expense related to the property you already own until you have identified the next property you want to buy (once identified, costs are added to the basis mentioned above).

Not to mention any damages to the property I will have to suffer as well.

The location all in,cost him X; he got an appraisal for the bank from CBRE national firmof XX and now the firm who called him mentioned paying XXX.

I’ve heard David Green mention it in a podcast recently.  

I talked to my lender contact and, as Kerry mentioned above, it's pretty uncommon that a traditional lender would offer a HELOC product on an investment property (non-primary home). 

I don't even mention interest.I did this recently and the guy picked the higher price with him carrying the mortgage for 5 years with no interest.Turns out a probate for one of his parents needed to be done so we are paying for this.

Local market knowledge is absolutely critical, and it helps to work with someone who really understands the landscape and its nuances.As others have mentioned, it’s a broad question that’s tough to answer succinctly, but I hope this provides some clarity!
