An effective way to understand that I've found is to set yourself a firm budget and put it into the search criteria on Redfin, start hearting or x ing out everything that looks like it would be a nice place to live, once you finish you can zoom out on the map and see where you have clusters of faded out bad houses and clusters of hearts, most cities I've done this with end up giving you a pretty good pattern.

I believe the loss of rent would allow me to pull the money out of the account even though my current job where the 403b account is held has not been negatively effected. 

is going to go into effect?

Because with my $20-30k purchases that rent for $600-800, I have teachers, law enforcement and retirees where their income is not effected .  

This is the reason you have had this experience:USPAP 2018-2019, STANDARD 1: Real Property Appraisal, Development, Standards Rule 1-5 "When the value opinion to be developed is market value, an appraiser must, if such information is available tothe appraiser in the normal course of business:(a) analyze all agreements of sale, options, and listings of the subject property current as of the effectivedate of the appraisal; and(b) analyze all sales of the subject property that occurred within the three (3) years prior to the effective dateof the appraisal."

Its not because I think it will be a huge deal, mainly to thank them for being with me and to help them at least a little during this crazy time.The following is the beginning part of the email I just sent out to all my tenants (for the properties that I self manage):Tenant's name,Effective now, I will be offering the following credits:Rent submitted 5 days early (by the 26th of the prior month) - 10% DISCOUNTRent submitted on time (by the 1st of the month rent is due) - 5% DISCOUNTI will be waiving late fees.

There was this notion that other investors would be effected, but not me.  

I have been working my HP 10bii to arrive at the Effective Rate/Yield on purchase of a note with a balloon. 

We use the aerosol bug bombs (1 in every room) and those have been effective.
