Hey Hilary!
I'm new to investing too but I think I could offer some help to you. I'm currently offering on properties, working negotiations and trying to get my first flip here in Tampa. While nothing has came to fruition yet, I'm hopeful that it's coming soon. Consistent action, right?
Anyways here's my answers to your questions:
1. Hard money lenders are all over the place and some are even tied to wholesalers. The HML that are tied to wholesalers are usually helpful if you can find a deal through them. They offer special perks and better terms usually. I did a lot of researching for HML and I have about 3-4 on my list that I think would work for any project. Their terms are different but I run the numbers using the best one. They're all pretty close though. My tip here is call a ton of them and get rates from all over the place. I built a mini speadsheet of 20 HML and I called them all. I put the rates in the speadsheet and compared. It helped me narrow it down from 20 to 3-4. I also got a proof of funds from one HML so I can attach it to my offers.
2. Finding deals are the part I'm struggling with - mostly because I'm offering way below their asking price. Better to make my numbers work. Set your price and don't let emotion make you bid higher. Find wholesalers, setup strict MLS searches, and network
3. I just got my real estate license about 2 weeks ago so I could negotiate and offer on whatever I want to. Plus I can look at houses whenever I want and save a couple thousand on commission. Might be better to activate it if that means you'll take more action. At least that was my reasoning..
4. I thought about the GC license too but I thought I wouldn't get it because then I'd fall into the trap of 'doing-it-all'. After years of studying entrepreneurship, i hear this is a common trap you don't want to fall into. I work for a large GC right now and I feel like I have the experience to manage some sub-contractors myself.
5. read that book asap! I loved it. I devoured the information in that book and reread it. I recommend getting the hard-copy though. It's easier to reference later. Other advice: consistent action.
I'm still working on my first one, but this is what i've learned so far. I hope it helps!
