Considering you are young, perhaps consider house-hacking a property in a good location, then converting that property to a rental and doing it again every year or two until you're too old to want to live with housemates or in a multifamily building anymore.

However, this needs to be converted to rental property before you can do the 1031 exchange.You might not even need a 1031 Exchange as you can avoid most of the appreciation on this property under section 121 even if you rent it out for the next three years before selling.

I' 'd be curious to see how much money down would convert a deal from unacceptable into acceptable in this environment.

I would sell your recent primary and do not convert it to a rental.  

I’m currently observing an interesting trend in the Central Florida market where a noticeable number of short-term rentals are being converted into long-term rentals.

Has any in California converted a property in a similar situation.  

Has anyone converted a basement into a unit and rented to a traveling nurse if so what did you do during the construction of the basement to help reduce sound from the up stairs.

That said if you're looking at buying or converting into a multiunit, you should be able to at least break even with 2+ units if you're looking at doing mid-term (saw your other post).

***Update Here***Should I keep Or Sale Gut Flip in B- area.If I sale my new flip best I’ll get is 30k after 9 months.If I keep as a Long term rental I’ll have to convert the garage into a 1 bed cottage at an additional cost of $35k leaving a total of $107k left in this deal after 70% refi and closing cost.

I've noticed in my area that houses that have been converted into 2 units tend to sit on the market for much longer and sell for much less than traditional single family houses with similar sqft and finishes.
