I forget the number right now but if you are within I think 5 days from sale date the lender isn't obligated to reinstate, but still may.You may be able to delay the foreclosure by simply asking for more time, you are now the property owner and have some sway.A couple observations:You don't have title insurance as no title company will insure a trustee's deed in CA, so that won't help you.You won the auction based on your commitment to occupy the property (SB1079), so this is not a quick flip.To buy time and delay foreclosure you can file a stripped down bankruptcy.You can't stop payment on the 86k wining bid since you paid cash at the trustee sale.Generally trustee sale buyers don't have a real good feeling for the property condition, unless you do for some reason, so this is a wild card. 

My personal suggestion - given what I know of your finances would not be to try and do a BRRRR - especially if you have never done one.  

Personally I would hustle and save money.

I've never been the landlord for a commercial property but have leased commercial property before - I leased through a commercial real estate agent who was acting as a leasing agent for the property owner, and the property owner was the one who collected my rent and is who I made repair requests to so personally haven't dealt with a Commercial PM before but will continue to follow this thread to learn more!

If you’re still working through it, I’m happy to share what I’ve learned—feel free to reach out! 

I do not know if your area has any rules against this for SFR but what we have done in the past from a marketing POV is to only bill 75% of the cost so that the tenant feels that they are getting a better deal than individual meters.

You might talk with the realtor and feel "pushed"....like the seller probably already felt when you approached him (maybe?

What's at risk is it may not cash flow and renting is not so common in South Jersey, but I would feel more comfortable investing in a good area where schools are decent to good, and tenants are likely to care more.

But, especially in this high demand market, you need to cast as many nets as possible and, likely, take on what feels like more risk.

I personally would go with cedar and have vertical posts spaced 5 inches apart.
