After you talk to the first one write down all of the millions of pieces of information they ask for and put a form / spreadsheet together listing all the details of your properties (ie: address, size, age, brick/frame, alarms, age of roof, etc). other brokers are going to need the same info.

Part of it is likely due to state wide quarantine restrictions limiting the ability to do much of anything, and the other part is likely being at home with a newborn and 2 other children under the age of 5.

These areas of concern would at least include:Verifying tenant informationfull names and ages of all residents and petsup-to-date employment informationaccurate phone and email addressesemergency contact infoVerifying the lease agreementrent amountstart dateend datesecurity deposit paidVerifying property repair statusoutstanding repair requestsunaddressed conditionsknown problemrepair promises madedeferred maintenanceHope this helps (or at least adds some items to your list!).

We recently got orders and had planned on renting out our house however after taking into consideration that age of the home, we decided selling would be in our best interest.

This can be dealt with in a couple ways including accessing its value (age, condition) compared to other commercial properties that have sold in the same area or using the mid point cap rate.Any large commercial broker familiar with the area of the properties should be able to provide cap rate range for each property.Commercial property valuation is so much easier than SFR to quad.I have seen sellers try to use a projected NOI but this is bogus. 

Age old debate diversify vs economy of scale.

@Justin HerringtonSlick acronyms aside, buying smartly and forcing appreciation is an age-old strategy which can work almost anywhere.

Hello, I'd like advice from experienced investors on how I should invest $100,000 in San Diego, CA.  1) Should I use it to upgrade my aging, dated, duplex in order to command slightly higher rent?  

Average age of death is currently 78.7 years and the baby boomers range from 1946-1964. 

If a deal just looks "OK" I  will still play with the numbers to see what my break even point is and what would have to happen to get there - if there are too many red flags then I walk away - there are still many other factors that I will look at such as location, age of property, type of property , local comps, ARV , potential add-ons  and other factors that would affect the cashflow and/or resell value.
