By doing this you'll start to see which strategies might better align with your resources (time, money, energy, connections, etc) and your future goals.

Ever heard of division of labor, free trade theory, efficient market hypothesis?  

Hi, I am looking to buy or build a small home with a business below, in the most cost efficient way.

**Energy Efficiency Grants**: Look into local and federal grants for energy-efficient improvements.

The property could be more or less efficient with utilities.

So I am not sure whether I really need sources of passive income right now considering that I have a lot of energy that I can spend on investment strategies that require more efforts and energy.

Your clients are motivated sellers.You can NOT convert people who do not want to sell  (below market value) into people willing to sell below market value.The mistake people make (constantly) is their efforts are based on forcing non-motivated sellers to sell, by constant harassment.This is wrong.Instead of mass mailing blanket mailing,  and putting your energy in finding random people and forcing them to become motivated by putting a ton of effort and money into follow-up, you need to focus on targeting the RIGHT people.People who are actually looking for your service.Hopefully, it changes your perspective and you can improve your business.

Most leases you can purchase are generic in nature and do not equip you with very helpful tools to manage your property in the most effective and efficient manner, lowering costs, reducing liabilities, creating revenue centers, etc. 

It’s also up to the architect to address the comments and resubmit the plans efficiently. 

Evaluate the numbers and your time energy lifestyle for managing rentals out of state and how those align with your why you're investing in RE.
