This property has a ton of deferred maintenance but I'm purchasing it well below market value and I have a decent budget. 

It helps readers a lot by providing context, and those of us who have some time in the market can look back into our histories and give you some advice. 

I'm interested in doing more HUD-VASH deals, and Sacramento is a market I’ve been exploring.

Got lucky with timing and market conditions... did a few then rolled the proceeds into my first MHP.Wow nice!!

All look in-line with typical market pricing.

Im not familiar with your specific market but if you have not checked out the events section I would start there. 

In CA (my market) the seller is required to make honest disclosure statement and you can collect for material non-disclosure.I suspect you already have learned that you need to check the status of all permits. 

Low or no down, seller financing and low or no interest with a balloon payment later is the holy grail (location, building condition, market also matter but it sounds like you have all that).

Hey All, I'll be traveling to Costa Rica for a wedding  and wanted to explore the market while I'm visiting.

Next property will find a professional Realtor who is experienced with marketing their listings and closing deals.
