HOWEVER..I'm getting a fair number of deals with significant cashflow and equity that make these amazing buy-and-hold opportunities at 2 and 3% interest.

Wholesalers (no offense to those in the comments) who are doing this without being a foreign entity are probably co-wholesaling which is on the borderline and practically acting as an agent without a license or getting referral fees by having actual wholesalers on the ground doing deals and they just provide the leads which is different than wholesaling.

In which case you can get 5% on 3 month CD.

I am just getting started, but willing to learn as much as possible.

That's just my opinion, some will say with the right deal go get that 100 unit deal

Get ready for a month full of learning, networking, and real estate opportunities.

What I've had clients do in the past is make an offer without a financing contingency where they tell the seller that they are getting a mortgage to close the deal, but also provide proof of assets to show that they can/will close by liquidating the assets if the loan gets declined.

It also helps to show them the amount of interest they can get when they add up 30 years of payments (compared to the sales price). 

You can get more bang for your buck. 

That was the right move for us at the time, but let me tell you, boy oh boy does it hurt every time I realize i sold a 3 bed 2.5bath home in dublin schools that I bought for under $200K...its the one that got away and honestly will haunt me forever...or until i go back and get it again...but seriously find a way to keep that thing fo the long term especially with that rate.
