Most property management software solutions are going to include ACH payments and some even have cash payment options where the tenant pays at 711, Walmart, CVS, etc and it electronically deposits into your account.Here's some software options that I commonly see recommended on BiggerPockets.

@Thomas HickeyHaving ungrounded wiring can be problematic with some modern electronic devices, so the first folks to find problems will likely be tenants.I would check with your insurance provider as they are the second most likely group to provide encouragement ("carrot") to upgrade the electrical ... particularly if you have knob-n-tube.Code enforcement will likely be third in-line in with a predominately "stick" approach to compel an upgrade, but in any jurisdiction where we operate these things do not usually "kick-in" until you "touch" something  (i.e. electrical or the walls themselves).You could look into the possibility of using GFCI outlets as a work around.  

Following are some of the similarities and differences between a self-directed IRA and the self-directed solo 401(k) plan:The Self-Directed IRA and Solo 401k SimilaritiesBoth were created by congress for individuals to save for retirement;Both may be invested in alternative investments such as real estate, precious metals tax liens, promissory notes, private company shares, and stocks and mutual funds, to name a few;Both allow for Roth contributions;Both are subject to prohibited transaction rules;Both are subject to federal taxes at time of distribution;Both allow for checkbook control for placing alternative investments;Both may be invested in annuities;Both are protected from creditors;Both allow for nondeductible contributions;Both are prohibited from investing in assets listed under I.R.C. 408(m)The Self-Directed IRA and Solo 401k DifferencesIn order to open a solo 401k, self-employment, whether on a part-time or full-time basis, is required;To open a self-directed IRA, self-employment income is not required;In order to gain IRA checkbook control over the self-directed IRA funds, a limited liability company (IRA LLC) must be utilized;The solo 401k allows for checkbook control from the onset;The solo 401k allows for personal loan known as a solo 401k loan;It is prohibited to borrow from your IRA;The Solo 401k may be invested in life insurance;The self-directed IRA may not be invested in life insurance;The solo 401k allow for high contribution amounts (for 2017, the solo 401k contribution limit is $54,000, whereas the self-directed IRA contribution limit is $5,500);The solo 401k business owner can serve as trustee of the solo 401k;The self-directed IRA participant/owner may not serve as trustee or custodian of her IRA; instead, a trust company or bank institution is required;When distributions commence from the solo 401k a mandatory 20% of federal taxes must be withheld from each distribution and submitted electronically to the IRS by the 15th of the month following the date of each distribution;Rollovers and/or transfers from IRAs or qualified plans (e.g., former employer 401k) to a solo 401k are not reported on Form 5498, but rather on Form 5500-EZ, but only if the air market value of the solo 401k exceeds $250K as of the end of the plan year (generally 12/31);When funds are rolled over or transferred from an IRA or 401k to a self-directed IRA, the amount deposited into the self-directed IRA is reported on Form 5498 by the receiving self-directed IRA custodian by May of the year following the rollover/transfer.Rollovers (provided the 60 day rollover window is satisfied) from an IRA to a Solo 401k or self-directed IRA are reported on lines 15a and 15b of Form 1040;Pre-tax IRA contributions on reported on line 32 of Form 1040;Pre-tax solo 401k contributions are reported on line 28 of Form 1040;Roth solo 401k funds are subject to RMDs;A Roth 401k may be transferred to a Roth IRA (Note that from a planning perspective, it may be advantageous to transfer Roth Solo 401k funds to a Roth IRA before turning age 70 ½ in order to escape the Roth RMD requirement applicable to Roth 401k contributions including Roth Solo 401k contributions and earnings.)

If you paid electronically, as in PayPal

You email the applicant from the website and they approve the check and pay the fee in advance on the website for you:https://www.mysmartmove.com/$30 background credit check paid for by applicant or landlord (your choice)http://www.rentingauthority.com/$25 paid by applicant, emails approval to applicant to pay with cc and includes electronic application form too.

It also puts the onus on them to actually send it back to me with the reduced rent (have not given one to someone that pays electronically yet).I got the idea from a landlord blog a few years back but can't tell you exactly where.

Hi,  I personally don't give anything, if I do it's electronic card or something simple.

@Karen Margrave,Effective March 1, 2013: Social Security Checks will stop Coming via the US Mail.Here are a few links concerning that:No more Paper Checks for Social Security effective March 1, 2013No More Paper Checks for Social Security effective March 1, 2013Also,When I signed up for my SS retirement check, they Informed me that I would receive the Electronic Payment on the 9th of the Month.

Most people (reasonably) expect that an electronic transfer is immediate.

Do you boycott everything electronic because one of its founding inventors was a racist ("the fruit of the poisonous tree")?
