Personally, I started off getting referrals from other real estate investors when building my team but eventually found and added my own people to my network over time.

My advice would be to start small and do your research.

Quote from @Cade Antonucci: I am starting to grow my rental portfolio and am looking for online alternatives to hold security deposits.

Unfortunately, with the number of pivots that are publicized and at inexperienced investor’s disposal, there’s never been more avenues for inexperienced investors to hold on too long.I hope inexperienced investors are mindful of this because I am constantly interacting with investors who are falling for these traps and doing immense harm to themselves, even if they may not be fully aware at the time of their decisions.It's crucial for investors, especially those just starting out, to recognize that not every investment will pan out as hoped (unlike what the gurus will tell you).

The seller offered financing with 20% down, which I used to buy the place.After starting construction and realizing it was going to cost more than expected, I approached a small local bank that knew the property and would offer the rehab financing. 

I will definitely check out IMPACT Grapevine and start attending some event to network. 

Over time your Tampa investment will start to cash flow.

Excellent start. 

another issue it is about 18 months wait to get a Cabin started due to high demand for builder.  

I'd feel comfortable investing ~$50k to start off.
