You would also need to weigh the risk factor for each investment.

If the market tanks (rents are currently in depression while prices remain at all time highs in my areas) it would be for different factors, at least in my opinion.

Not sure the type of return you are expecting but with the purchase price and units provided definitely make sure you account for all factors prior to moving forward if you choose to.

This is not your best option as then each unit is tied together and an exit strat becomes more time consuming and difficult to do because your lender is now the deciding factor in splitting the loan apart if you choose to sell. 

@Lisa Beard In order to factor this into the deal, you would include a line item for property management in your deal analysis / underwriting.

There are other factors at play than just the cash flow! 

In the future they will make large pickup trucks that need this, and they must fit where the charger is.Also, know what the service life and repair costs are for this equipment and factor those into your CAPEX and repairs budgets.Make sure the equipment you are installing is the equipment you want to offer to other renters in the future.

@Nick Louie You can try to negotiate any terms you want, but don't be surprised if the seller thinks your offer isn't worth the extra hassle and backs out.In my opinion, you're better off asking for the standard "broom clean" and factoring in the cost for a professional deep cleaning.In a hot seller's market, your strategy should be to be as pleasant and cooperative as possible. 

Just factor into your calculations that all rental income is taxed at regular income rates, and you will have additional costs when you sell the property.

Should something happen even out of your control the "What if factor" and you miss any payment on any debt on credit.
