I want to take advantage of growth if possible, but also want to minimize taxes and fees (penalties).

What is your credit score?

Zero capital gain tax, next to zero income tax, property Tax is super small.  

I've been using the GE  GFW148SSMWW // GFT14ESSMWW models which comes to $1,650+ tax for units and stacking kit. 

I paid tax on it and mowed it about every 5 years so maybe put 10k into over the years.. deductive reasoning suggested city does not build and full blown interchange to go to nowhere. 

Ask for a line of credit.  

So if you have the property for a total of 10 years, moved in at year 8, little value or tax advantage.

Leverage Local ResourcesEconomic Development Grants: Check with your city or county for grants or incentives aimed at affordable housing or community improvement projects.Local Banks or Credit Unions: They may be more flexible than larger financial institutions, especially if your project aligns with community needs.Partnership with Nonprofits: Collaborate with organizations interested in affordable housing or sustainable living.4.

As someone mentioned, the only thing passive about real estate investing is the tax treatment. 

So my question is, if you were in my shoes, where would you start if you had $150 cash with good credit?
