Another alternative is just finding a good number with repeating digits that is easy to remember - not as easy to remember as words perhaps, but maybe easier to call at the time they see the sign (vs. trying to figure out numbers for letters.) 

I looked into digital locks and the cost is very high when you have two doors per apartment.Doorbells - with the old houses the wiring is old and frail.  

Something along the lines of "5% if we have to pay a cooperating agent, but we'll reduce that to 4% if we keep both sides of the deal" - But clearly, we're talking single digit savings here, which is normally not going to allow you to negotiate a huge discount just because you are unrepresented.)In many cases, the view of the listing agent/broker is If I'm dealing with an unrepresented buyer, that just means I have to do three times as much work to close this deal (because now I have to do my own work as the listing agent, in addition to all of the stuff the buyer's agent would normally do)...Many (especially high volume) listing agents don't like working with buyers, lenders, inspectors, and appraisers, and all the other plates the buyer's agent has to keep in the air, and would actually prefer to just pay the commission and have a strong buyer's agent keep everything on track. 

I usually advise my clients to do 506b unless they have great marketing chops or plan to spend a lot in hiring digital marketing experts.

Everyone has different obstacles so how to spend your time should be specific to what you need to overcome. highest ROI time investments would be education, active local and digital networking weekly (if not daily), learning to raise money, and content creation. write out a strategy, and then determine what is in your way from accomplishing that.

One resident was slightly late for a few months as they temporarily lost their auto repair job,  but were rehired and caught up.There are definitely some freeloaders/opportunists out there,  but they are a small minority  (low single digits percentage if not sub 1%) - no comfort if you happen to have one of them -  but odds are fairly low.   

I’m wondering if there is a way to manage by a digital key pad in the front door and having the renter check it out for themselves.  

In YOUR situation with your $125k, I would invest it in RE loans at double digit returns.

I print my TREC PDF to efax, (it becomes a digital copy).Then in the efax document I can put in a text box anywhere I want, and fill it in.

**My friends niece is realtor=full comps**Digital Pics - Full interior / exterior PicsU get the idea...The more you do for the investor the more u can get $$.It things they will have to do eventually anyway.Some investors are stingy and greedy and don’t want to pay so gather your list (of investors) ahead of time and isolate into groups or categories…It’s important to send your properties to the right people first.One last idea I got from Washington Real Estate Mogul (Joe Kaiser) was called "Pre-Habbing".
