With Fidelity 401k plan you will be limited only to Fidelity investment offerings, to invest in real estate and other alternative investments you need truly self-directed Solo 401k plan.

How often do they have special assessment, do they have good reserves, will they change the rules to limit or ban rentals?  

If you are self-employed or own a small business - you will be eligible for a truly self-directed Solo 401k plan, which is exempt from UBIT on leveraged real estate, has contribution limit nearly 10X higher compared to an IRA and number of other benefits. 

Hi everyone, I've traditionally stuck to long term buy and holds that have required limited repairs/ improvements and have not gone through the refi process as yet.

you can close approx 35 days after owner gives the tenant a 90 day notice if they are willing to do that.2.) yes, there is a yearly rent raise limit.

Purchase a duplex in San Diego and live in one unit - PROS: essentially get help paying my mortgage via rental income, proximity to rental property, maximizing FHA loan on a more expensive property (maximizing my down payment in a low interest rt environment) CONS: The market is so unbelievably expensive and rents are not comparatively high enough to really make most moves profitable, high Debt to Income ratio thereby limiting my ability to purchase again2.

But next of kin close family is where I would be going if you can get to them and see whats up.If the whole family has limited resources may not be much help there.I know when my mom was in the same situation the corporate owners would not cut her an ounce of slack so I paid her rent for years. 

This 1: helps society out, getting more people vaccinated but 2 and perhaps more important to landlords: limits your risk.

@Wendy Thurst I would say if you have a partner already just look to close it with your cash price and try to limit the number of people you split the profits with.

But they live in CA, so it's hard for them to get either, they are limited and expensive.
