This requires a dedicated effort sourcing and analyzing hundreds of deals to find the one or two worth pursuing.  

I'm still in the process of growing my portfolio, but have heard others 1031 all their smaller properties into a larger building and have a property management company manage, OR, set up a seller financing deal with another buyer that gives you the cash flow you desire. 

The best opportunities in the Mansion are the parts where it borders an area that is at higher scale in my opinion.

I’m happy to share my own tips and experiences as well.

Make sure you talk to a Banker or Loan officer that is well versed in both SE (Self Employed) income and also Non/QM programs.One tip I will give you as a Banker is open up a "Business Checking account" and for the next 12 months pay "Everything" out of that account. 

I would imagine most misrepresent their sources and uses when they apply for their financing.

If you want please feel free to add me to your Network would love to be part of the team and I am always happy to help and offer advice or tips on my side of the finance part of things!

I'd use an approved underlayment.Pro Tip: If it's cheap, it's not good.....at least spend in the moderate range.

I’m really trying to get to the top in of my buy window (1.1m).

If you offer more $ for the property than the all cash offers AND you appear to the seller to be highly qualified in the method you are using for sourcing the payment, at some point your offer will be more appealing than the all cash offers.I don't understand why you would consider a 1031 for another property in two years.
