Anything else is simply going to complicate your books and increase your taxes.

One complication is that taxation from real estate can be different for a foreign national investing in US real estate.

It complicates things for everyone and will make you appear like a real cheapskate to your tenants in a way that just raising the rent by that amount would not. 

This will reduce the possibility that you get stuck with a troubled tenant that calls you for unnecessary items to fix or replace (i.e. a light bulb).

For my 4 properties, we cash flow about $3000/month that goes into a pot that we just grow and grow and use to buy other properties.  10% CAPEX, in our experience, is a bit much and frankly unnecessary.  

A lot of investors setup a new LLC for each flip which does offer flexibility, but also some unnecessary paperwork and fees.

Hi Guys,I'm in the process of selling a property to an acquaintance in a somewhat complicated deal.  

Almost, as important if you hit the lottery and get the home itself for what is probably a small sum having the other lien will hugely complicate your life.I certainly agree about using an outside company that was my point.

So if seller financing is a possibility should I get a lawyer to do the paper work and legal stuff or is it unnecessary?

And the cost of renovating with the additional Boston complications can turn your cash reserves into smoke.
