I live close to my tenants and we have a procedure whereby they text if it's something small and they will usually just take care of it themselves and I will pay they for time and materials but if it's something like a broken pipe or the furnace not working they will more than likely call and I'll get a repairman to come out.

When you ask about tax liens/certificates/deeds you need to specify the state, as all procedures/laws are different.

You do have to spend a lot of research, time and experience to learn the specific laws and bidding procedures for the state you want to invest in.

Nothing against plumbing or carpentry, but based on easily mitigated through proper procedure increased pay for bodily risk, plus the benefits of being able to upgrade your own properties, I see electrician as the most desirable of trades.

. - Clearly define payment procedures - As some of the folks before me have said, some projects could be 1/3 at the start, 1/3 halfway through and 1/3 at the end or you could pay the entire project at the end.

Normally operations with over 500+ doors UM will have these procedures in place. 

Quicker turnover time/reduced vacancy, better tenants, better marketing, knowing market rent and market conditions and typically better access to vendors who will go the extra mile for 500 customers vs. 1.  2) It keeps them out of court and unnecessary litigation with extensive knowledge, process and procedure that a private landlord cannot match. 

Along with the paperwork required to raise rents and the rental registration procedures it makes operating there quite challenging hence why I personally don’t recommend it to a newer investor.

However, you will need to have to make mistakes and over time write your own procedures and guidelines.

Just simply the volume of things we see, builds our experience and allows us to have continuously improved processes and procedures versus an investor.
