I've been monitoring auctioned foreclosure homes in Las Vegas and haven't really found any deals that are worth it.

By doing this, not only are you increasing the value hopefully building you some equity (giving you some boost in your net worth) but also increase rental potential too. 

I purchased a 4 unit in Dec 2021 in Pt Loma (Worth ~$2.5M then, now worth ~$3.4m). 

DSCR loans are based off of down payment, credit score and either actual or market rents so it helps to supercharge an investor's real estate goals and net worth.

What have you found is worth the money and what isn’t?

If you can find comps that support a lower assessed value, it's worth trying to appeal.

I have been looking at sf homes with comparable SqFt to one of the units, as well as the units combined to try and get a feel for what this is worth.

So they double or triple the rent, then what’s e trailer worth?

@Mickael Castillo It's worth a try, but IME investors like that will probably blow you off.

You'll have to ditch the seller financing and have skin in the game.Freddie also requires that borrowers meet minimum financial strength requirements (IE - liquid assets equal to 9 month's P&I [bare minimum], net worth greater than or equal to loan amount [bare minimum], FICO>=680).
