Always best to have a professional buffer .Lots of people can do lots of things but alway better to have few people do fewer things .

Your units will be well landscaped and they will provide anoise buffer with the railroad.G.

A builder may not know all of the overlapping aspects that affect the build and design - setbacks and buffers for example.Thanks, this was very beneficial.

Typically you have wetlands and then you have a buffer or setback from the boundary so even if your property isn’t in the wetland it might be in the buffer as not a buildable site.

Since there is uncertainty with the Fed raising rates, elections coming up, inflation, etc. we are baking in a big buffer on the ARV.

@Gary Miller Since it meets the 2% rule, it should give you enough buffer to make some mistakes and still find cash flow.

I think six months rent is a safer buffer.

Finally, I like having a true buffer between myself and my tenants. 

This can provide a buffer against potential declines in property values.

Renters don't usually have much of a financial buffer, so they may not have the reserves to pay prior to being paid.What might be convenient for them is the ability to pay by automatic payment of some type or PayPal or some other service like that, rather than a check - in case that might be an issue.I always found that if I just sat down and talked to tenants like they were smart people who were capable of working something out with me, with an attitude of respect, it almost always worked out.So you could sit down with them and tell them that your mortgage payment is due on the 5th (or whatever), and you could possibly lose the property if you weren't paid by then, because your finances are really tight.
