I have my fathers trust in this matter so using it as an opportunity to help him and learn for myself as this would be a new type of transaction for me.  

The property had been vacant for years and at some point the city had tagged it as effectively “condemned” until certain code violations were resolved.

No sub will be effective via email in the field, it's just too hard to be out on site and answer emails from you iPhone.

This is a deed from one person (grantor) to another (grantee) that takes effect only on death of the grantor. 

@Harrison CookYour post kindles lots of questions.In the "good old-days" most heating systems were vastly oversized for the building they were heating - energy was relatively cheap, insulation was non-existant to poor ... so it was easier and safer to {drastically} oversize.Today, while energy {in North America}  is still relatively cheap for the moment,  we have a much better understanding of how to make buildings more efficient {though you might not think so looking at the construction industry in the U.S.A. and Canada}  and there are often more cost-effective measures than simply replacing an old, over-sized heating plant with a new, over-sized heating plant.You really need to - or at lease should -  perform a heat load analysis to properly size your heating system, a component of which, is determining the rate of heat loss of the building envelope.  

You could do that now or wait until you think the market is more tilted towards buyers, the only effect on you will be rising interest rates. 

Things like that will effect margins short and long term in varying ways.

Consideration must be exchanged for a transaction to even be legal.None of your money in the deal has an extremely high cost.

If you would throw in some Small Multifamily Units in the picture, you can not only have better income per door, but also achieve financial freedom and critical mass in less number of transactions.  

Because it is effective.
