Targeting that small an audience will not be easy.  

@Mike ReynoldsRegarding your comment that if you need funds you can use money from your side business:You can't use non-retirement funds to pay for expenses related to real estate held inside you Solo 401k.Subject to the contribution rules and income limitations, you may be able to contribute non-retirement funds to your Solo 401k (e.g. as an employee or employer contribution) and then you could use the funds in your 401k to pay for expenses related to real estate owned by your Solo 401k.

If you are paying cash for the STR this seems pretty easy. 

It's very easy to stay organized this way.

Its not as easy but once you are up in running you are building a brand, equity in your business, and also constant flow of leads.

I think new builds don't really work from an ROI standpoint, but if you can find properties that have easy ADU conversions then the value might be there.I'm in MA and we just made ADUs legal by right, so I'm looking into the best ways to add value using them.

Dimensional variances are usually the easiest to get, but that doesn't mean they are easy.

@Andrae S Wiggins recommend you upgrade your BP membership to Pro to access the BP Calculators to evaluate rental purchases.Play with the numbers to figure out the purchase price that gives you your target ROI.That's the number you'll need to make an offer at, NOT what the seller is asking.Yes, you will get a lot of rejects, but whoever said investing was easy?

Still tons of positive cash flowing deals that meet the 1% rule and amazing appreciation here!

Driving a car is legal, as long as you follow the rules.
