As an 18 year old just starting out in wholesaling, how could I build my credibility so sellers and buyers feel more comfortable and trust me when selling/ buying a home?

I haven't seen anything that indicates people do, but I was thinking it could be a good strategy if one is motivated to get an agreement in place.

It sounds like at this point your options may be to either: A) see if there are other forms of investing he could get on board with and start there to see if he grows more comfortable with time and experience or B) table the investing for now in order to preserve your marriage. 

We are clutching at straws here to find something indicating a little cooling in the market....Phoenix is currently the strongest large-city housing market in the USA and this is fueled by inter-state population movements.

You may need to send them a legal document indicating that you have taken possession of the house.

We don't have CPA yet and when we tried to consult couple of CPAs recommended to us, it was clear they have not dealt with investments and were not sure what to say, so we are not comfortable hiring them.Any clarification would be greatly appreciated!

Don't mistake these things for not taking action, they are critical for most people to feel comfortable to jump in, just like you would before starting any business.  

Find your comfort zone and pull the trigger.

@Lewis Anderson Are you comfortable working with your CPA remotely?

I'm breaking out of my comfort zone here, and hoping to gather a little bit of advice before I finalize a deal on a 14 unit mobile home park.
