Not saying you can do it while sitting on the couch, but one way is to buy stuff like this (listed on the MLS in this case):https://www.redfin.com/CA/San-Diego/3905-National-Ave-92113/home/147880176If you'd like to go through the exercise of penciling this out and posting, I'll share my POV on why a property like this makes sense.

It is unavoidable.Of course when handling Roundup (or any chemical), exercise caution.

A properly set-up DST will both protect your assets and bypass the burdensome franchise tax that would be levied against a Series LLC.The Delaware Act expressly provides that “[n]o creditor of the beneficial owner shall have any right to obtain possession of, or otherwise exercise legal or equitable remedies with respect to, the property of the statutory trust.” 12 Del.

Different states exercise their own regulations concerning what permits and licenses are necessary to flip homes and that the investors should research and know what type of permits and building requirements are enforced in the area.

Which basically tells the seller that you are going to do an inspection, but that the inspection is for informational purposes only and you will not request any repairs be completed by the seller.This clause also gives you your full right to do an inspection during the neogitated timeframe and if issues arise that make you not want to proceed your purchase you can exercise your inspection contingency and back out with your earnest money being returned by the seller.This is usually a compromise for someone who wants to make their offer more aggressive in the sellers eyes, but is not comfortable (based on experience or condition of the property or both) to submit an offer with no inspection contingency.I agree with @Mindy Jensen. 

If you both agree, you can stay month-to-month with a 3% increase or even exercise the option for another 5 years as long as it is documented properly. 

You're not "buying the home" until you, or someone else "exercises" the option to buy in the option contract.

By the time you need to exercise the option, hopefully you're in better shape.

The people are way more healthy than we are (probably a diet thing and exercise thing) with old people running across the streets and riding motos! 

And then the struggle to exercise/dance enough to make up for it, which can actually have the opposite effect (going between 2 extremes: sitting, and very strenuous movement).
