The new standards are yet to shake out I think and it probably does cause some indigestion for investors and agents both. 

@Michael ReilmanKohler and American Standard both make great toilets, but Kohler toilets have unique parts that you can't replace at Home Depot or Lowe's.

Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

One of the things to watch out with mobile home parks is the increase in lot rent.

.- They often get sold Class C or D properties while using Class A assumptions - then wonder why they are losing money.Here's some copy & paste info that you hopefully find helpful:-----------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

What would standard down the payment be? 

Also, watch out for any litigation or construction issues that could lead to HOA fee increases down the road.Alternatively, you could consider a good deal on a single-family home or a 2-4 unit property.

They are grandfathered in, the property was built prior to those standards.

However, San Diego is an extreme case.However rents increase fast in San Diego.  

When they eventually move out, I plan to do a full renovation to bring the unit up to high-quality standards and maximize its rental potential.I’m happy to connect if you ever want to chat.
