I want to become a private lender for a buyer of a condo in Orlando.

Please understand this (and I am not advocating using attorneys as a must) land trusts are very state specific and I would spend the money with a good experienced real estate attorney who is also an investor themselves.Spend a little more now verses a lot more later if it's not set up correctly.

I know the most successful wholesalers are spending tens of thousands of dollars each month in mailing campaigns. 

I would absolutely spend a little more for more durable products.  

Talk to your tax planner.The money spend on education has to be carefully evaluated.

@Anandakumar Elumalai  Just sent you a private note.

Rehab using private money, personal money, or family money, etc.3.

In short, I'm a private real estate investor.

@Darryl JacksonHow much you need can depend on many factors , the purchase price of the home , the rehab costs etc.Also if you are going to pay all cash or leverage ( hard money or private money loans etc ) If you don’t own your own home I’d suggest doing a live in flip or house hack as you can take advantage of low money down loans like an FHA loan for 3.5%Many people have used this as a way to start out and gain equity that they then use for other deals .It’s possible to do deals without your own money if you do a joint venture type deal but could be hard to find someone to partner without experience, might have to give up more than half the profit but still better than no deal .

I put a small downpayment down towards the condo and took a private loan from them that I am paying them back for 25% ownership.
