From there, research the general structure of a “business plan” and apply your new found knowledge to populating the template you select.There are no secrets or shortcuts, just due diligence, knowledge and the energy and initiative to apply them.

Taking short cuts now can lead to profits getting cut short later!

Eliminating applicants based on their possible level of delinquency is a short cut to screening all applicants. 

There are no shortcuts.

@Joseph Tarallo Mark is spot on - don't take a shortcut, remove and, if necessary, remediate.We walked away from a 28 unit building a couple of years ago due to two out-of-service USTs which the vendor did not disclose (he was the one who converting the complex to natural gas, so was aware of the oil tanks) and then refused to take responsibility for them.The property remains unsold, but it looks like he is now removing the tanks.The environmental liability of having unused/old USTs is not something you want.  

This may help shortcut your path to success.

The damage done from the "not so good ones", can be.Wholesaling isn't a shortcut, or a "light" version of REI.  

And I understand where that frustration comes from and it comes from mainly wannabe investors that spent a ton of money on some BS GURU course, and even if it was legit, these wannabes then try to take shortcuts, as I hope these "guru" courses are not promoting that people try to sell property they don't own.I completely agree that nobody should be trying to sell something they don't control.

But if something goes wrong and you've take shortcuts, you're probably getting sued.

All units have window air.1) Make certain the electrical was redone correctly an no shortcuts (i.e. splicing into existing knob-and-tube or ungrounded wiring was performed).2) Before replacing the boiler, see if each unit is on a separate zone.
