We have plenty of investors who invest in our investment fund using their SDIRA; especially now that the stock market is so high. 

Hi Lynne,Gunshot alley is no place to raise a family.If you want to move quickly and move up to a nicer lifestyle, there are a lot of LARGE Multi-family apartment complexes in the area.Many will have pools, hot tubs, gyms, dog walking parks, Amazon Delivery boxes, and the freedom from having to cut the grass or maintain the structure, and best of all no property taxes to deal with--all in return for one monthly fee.If this is something you are interested in, go visit a few properties (after dark) and see if they "Feel" safe to you at night.https://www.apartments.com/santa-rosa-ca/Just my 2 cents!  

The buildings have been well maintained and maybe 1/3 of the units have been completely remodeled in the last 3 years.

LLCs can be expensive to maintain. 

In my area well maintained doublewides on permanent foundations on their own land usually appraise for $100-175k and easily qualify for 30y mortgages.

We got a discussion from the fire inspector about the need to maintain the fire extinguisher via annual inspections (even though it worked) and about the need to inspect the various detectors at least annually. 

I have about 100k in stocks (retirement s&p) and I bought a 2 family house in May 2019 for 535k put down 20%, 30 year.

If its the same dated filter I installed at move out I'll charge the tenant for a service of the unit due to the added strain on the system they caused by not following our lease agreement.With your plumbing situation I would include a lease provision that states tenants are responsible for maintaining all plumbing, excluding root intrusion and the like.

All I need to do is deploy the savings into a new property or simply reinvest the money into the stock market for a higher return over the long term.

I remember a staying Warn Buffet said buy stocks when the market is down you are getting them at half price (something along these lines).
