I asked for measurements to arrange the replacement, but they took two weeks to respond.

There is no appreciation beyond that like you have in real estate, but it is the easy answer to your question at the moment… and inversely related to real estate, so as interest rates go down on savings, real estate affordability will go up by the same measure (more or less). 

However, without bug control measures, they can get out of control. 

It's a measure of cash flow relative to debt obligations.

An approach you might want to take, is to break down each component of the rehab into its own price per sqft/linear foot/units for both materials and for labor.for example you might find that flooring costs and average of $3.50/sqft labor to install + $3.00/sqft for materials X square feet = cost to refloor+ always add an extra 10% for unforseensSo you would just need to do this for every part of the rehab based on what needs to be done and what level of finish you are going for.keep in mind that some things are measured by sqft, like floor, and others are measured by linear foot, like trim, and some are measured by total area, like drywall and paint, and yet others are measured per each like tubs and toilets.A good place to start with figuring costs is The Book On Estimating Rehab Costs by J.

Novices are at the whims of REACTION vs proactive measure. - Negotiation.

I know because I was part of that measure, as I worked with Dr Without Borders getting N95 masks out as I scoured and found "hidden supplies" from various home services warehouses and got them out there into medical services circulation.

Even more are evicted informally.My company manages 400 rentals, and we evict less than 1% per year.How do you measure up?

Given the complexity of San Francisco and the eviction control measures that exist you do NOT want to do this on your own and need to make work with a landlord attorney to accomplish this. 

A good precautionary measure for everyone's safety.Also, there's a new rental management product on the market PropertyScale.com.
