Have you and your wife narrowed down what type of investing route you'd like to begin with? 

I see so many investors still going the old route of the local cabinet guy.

even if its interest only, id want to pay down principal here and there. seems like sellers would offer this interest only route so they have 0 capital gains tax, but id rather pay down a bit of principal in 7yrs. i see its not required but it should allow for principal paydown in promissary note3) any general advice to look out for on seller financing?

Are you finding motivated sellers via the typical route of using the prominant software platforms like propwire and propstream?

You could go the house hacking route with buying MFU, etc.It MIGHT be interesting if you are a traveling nurse to turn your house hack into a short term or mid term rental while you are gone.

I'm going the "wholesaler" route to find myself more deals to rehab and rent.

I really implore you to go another route as most arbitrage ends poorly. 

Is this possible or would I have to split the land and go that route?

If you decide to go the accountant/CPA route be sure to ask up front how much it will cost.

Looking for some input...I'm working on educating myself more when it comes to various tax benefits and trying to decide what would be the best route for me moving forward.
