@John Leeagree with being picky with where you live and your primary residence. 

-> Funding: you can consider as options mortage brokers who can scout/compare the best offers in the market and you can also consider public funding programmes that exists as an incentive to renovate and bring houses to the market, either for tourism or traditional rental.As an example, on the traditional rental there is a funding program ("Arrendamento Acessivel") that funds up to 90% of the project and can be used to cover part of the renovation costs, as well as, part of the purchasing.

As of lately, the traditional BRRRR is not working with the higher rates and low inventory as, others have mentioned. 

After they moved in, we started to get some mild complains from our neighbors (for the rented unit which was our primary residence until we moved out in another house a few miles away). 1.

You're likely better off attending your local REI meet-up to see if you can find an investor who has house-hacked or is currently house-hacking their primary home.

Pay it off and then buy a new primary and turn your current home in to a rental.

Or buy a 5bed/3bath house, live in the primary suite and rent the other spaces out.

I have a HELOC on my Texas primary residence and am considering a house hack for my next purchase.

Typically most DSCR lenders follow a traditional 5, 4, 3, 2, 1, PPP or a 3,2,1 PPP.

I am curious as to if anyone is aware of any first time home buyers programs for buying the first Primary Residence.
