There isn't enough information in here about the current state of the house to be able to advise you, but I would think #3 is a definite no as it seems unnecessary from a cost perspective although that market has scale to accept it.

(We lived in that house for years and in other properties we knew this was the case)Disposal: Was newly placed in property before tenant moved in.The fee: $145.We put the fee on the tenant's following month's rent as their responsibility due to resolution provided and plumber's confirmation that the disposal was working fine and structure had no issues.Tenant has disputed the charge, ("other landlords would be appreciative of our notice" "we don't eat a lot" "isn't that what a garbage disposal is for?

Something I forgot to mention is I’ve been in the house since 2017, so the 2/5 year rule shouldn’t matter.

Do you have a step by step list when looking at the potential house?

In regards to tenants, to putting the house on Section 8, to the selling of the property.

Cost $5,000I sent out 500 post cards on several occasions that I designed and bought two houses.

The house has a lot of deferred maintenance.

Get your CRM up and running and keep in contact with everyone with content about the market, keeping in touch with past clients - just asking them how their house is, let them know that you were thinking of them when you drove past the house,  ask them if they made any improvements, etc.

In most areas in San Diego, that is condos, town houses, etcWith that budget, I would be leery of recommending San Diego.

Currently, I’m actively expanding my portfolio in Austin, Tempa, Dallas, Houston, where I’ve seen significant growth and demand for multifamily housing.
