There are also supplement loan features built into commercial financing that allow cash out once the property has been re-positioned.The most important factor is the profit per property...profit per unit is not as relevant. 

My overall goal for investing is to earn enough passive income so that I do not need to "work", therefore enabling me to travel and see the world.  

Experience and knowledge may reduce the number of bad investments to a smaller per cent age, and may enable us to salvage the situation and minimize losses, but the “losers” are part of the business.

If you've got steam, things can get complicated, however you might be able to clean up your living area by removing the radiators and adding forced air.High velocity is a nice option if you have a finished basement or finished attic / 3rd floor.Finally, the mini-splits can be great to supplement heating and add cooling.

@Austin Janiszewski if your current primary (Property A) is renovated and will generate positive cash flow after renting, consider this scenario:Instead of selling, utilize Property A as a source of supplemental income to offset the higher interest rate environment.

We own a duplex rental property here in Virginia Beach and are mostly of the buy/hold mentality to supplement eventual retirement income in 6 years.

They planned to buy a large apartment house and operate it through a property manager, providing them a nice cash flow to supplement their other retirement income.

Also we would make provisions that would enable my mother to call a portion of the loan due at one time to cover her retirement/expense, i.e. $50,000 in any 1 year period.

Typically they will be able to qualify 75% of the rent as supplemental income.

This enables you to take maybe 2%-3% back off the sale.
