Emphasis on knowing your numbers.. a cash buyer(the one you assign the contract to and is actually going to buy it) will expect you to have run the numbers and save the cash buyer the time, that is the value you bring to them as a wholesaler.

Do it in writing, insist all communication from them be in writing or via text and save everything for future court use. 

I have a 3.625 rate now and am hoping to rent it out in 2 years if I can save enough cash in the mean time for a new home.

If you can put 3-5% down on a multifamily you may be able to move forward with an FHA loan, if you are not willing to live in the property or if the property is out of state you will probably have to save up much more. 

I save time during the day to talk to BP Nation members.I love this stuff!!

I'd continue to save money while learning, building a network, and searching for a great deal.

We have good, not great credit, and a decent amount of savings that we're hoping to continue to increase.

I would do this if it meant saving enough on purchase price to justify the seasoning period, the interest rate risk, and I still had adequate reserves to cover costs and expenses.However if you aren't able to see real savings on our has price then you should finance it and use Heloc for down payment only.

Saves you both from any negative feelings or fallout if the two of you just "waited it out."

Your biggest challenge, in my opinion ( and what I am currently facing now) is the amount of money you have saved and coming in as well as being young.
