Of course, your opinion is just as valid as mine, and if it works for you, that's all well and good.True, you definitely do NOT want to give up a 3% loan....BUT there are numerous CREATIVE ways to build net worth FASTER than hold and reinvest cash flow.  

However, for us usually the late fee is $100 on the 5th and then another $5-10 per day they are late to incentive getting it in faster.

This will be much faster.

These normally come in a little lower than a full appraisal, but are faster and cheaper (pro/con). 

In terms of vanilla transactions, they are ok and will close, but there are better, cheaper, faster options out there.  

This approach provides financial stability and lets you focus on paying off your 4.75% mortgage faster.

Instead of going all-in on one deal, consider using financing to spread your funds across multiple properties to scale faster.

If you seller finance you no longer own the property but instead own the note which are more passive, no repairs, no maintenance, no tenant calls, little to no liability, more liquid (can sell faster to get your money back if need be), very scalable and less cost to manage the asset.

This scales faster in the short-run but you'll quickly run out of capital and be stuck saving cash flow (and other income) to buy the next rental.I hope that helps.

But, It’s truly is one of the three reasons I use a PM for the rest  1) I don’t want to screen, I don’t really like meeting new people.2) I want to stay legal in my screening, notices, demands, etc etc3) They raise rents more and faster than I would and collect more in late fees.They literally pay for themselves with increased rent/fees and I get the legal and people screening for free.
