@Bracken Bjorn The answer is in the local data...and the data might look differently to you than someone else...it's really about your goals, tolerance for risk, available resources, and personal preference...

I prefered two or three more years that I can work and save money to buy a house ( $300k) and car (30k) with cash.

You can also horseback with a single family...it's completely a personal preference based on what you are comfortable with.  

Efficient Renovations: Focused on high-impact upgrades like modernizing the kitchen and bathrooms, improving curb appeal, and installing energy-efficient features, which are highly desirable in this competitive market.Optimizing Layout: Evaluated the property's layout to ensure it met modern buyer preferences, such as creating open-concept spaces.

Or any other options you prefer such as a 1031 exchange?

I prefer properties that are heavily focused on the residential component  because mix-use assets receive far less attention than multi-family assets.

However, in the long run, I love the "buy a house a year" strategy (as a primary, for preferred financing) and just keep moving (pending that your spouse is on board with this of course, if you have one).

Personally I'd prefer a single family over a condo just because of the control aspect and HOA nuisance. 

I recommend you consult with a lender with expertise in investing, preferably someone local to you, to discuss the lending options best suited for your goals, strategy, and tactics.

Prefer to cashflow as close to day #1 as possible.No problem!
