I've been in real estate since 2015 and currently offer accounting services to investors.

There's nothing better than getting an FHA or conventional offer accepted by an unsuspecting seller, knowing you will have plenty of opportunity to re negotiate once the appraisal comes back.

Seller is an idiot for even accepting your offer.

Happy to offer up some more insights if you're interested.

Admittedly I am new to this and I haven't written a creative offer before. 

Focus on how to juice cash flow if possible (rent by the room, separating spaces, etc.) or decreasing expenses (assuming a loan, looking at new build incentives, aggressive offers w/ rate buy downs that work for you, etc.) 

He is a mentor of mine as well, and is not so interested in making money but rather he told me that he likes to see 7% in his passively invested accounts, so I offered and he accepted that I would pay him 8% APY On the principal that I borrowed. 

Turnkeys offer less hands-on management which is ideal for beginners and it give you valuable experience as a landlord.

We just made an offer on our first deal.

You can explain to the Realtor that if you don't do this, then it has to be a cash buyer and they will offer less.
