@Vlibhu Arya Proper and professional Property Management encompasses a wide range of tasks including requests for repairs.

It appears newer triplexes require sprinklers and Siamese water connectors out front, building wide fire alarms etc. 

The broad SSgt tier is my preferred tenant, whereas the bottom tier of new-from-basic training sailor, airman, soldier does not have life experience to take care of my properties, money or ability to pay my rents.  

Looking for about $25,000 all in for each, single wide 3br/2ba suit the area best but may be able to do a few small doubles.

Assuming the owner is correct on being able to split the lot...I did this in WPB, about $4200 with the process and the special survey/replat required, there probably is  no market for the cost of a new build in that price neighborhood.....having a gc build a standard house is probably $140/sf plus design, site prep, impact fees, etc.The one I did already had two houses on one 150’ wide lot.

Any tips, books, courses for beginners etc are always welcome as I am approaching this wide-eyed and curious!

I have some new younger tenants who have been leaving their windows wide open while they are gone at work all day.

Oregon just passed state wide rent control. although its mainly moot it allows rents to rise higher per year than what is reality in the free market.. were it does affect is those looking for value add situations  IE syndicaators looking to snag troubled properties raise rents real quick and retrade.. that could be tough.  

It's better to go into this eyes wide open so that even if you manage it yourself now (which will keep a nice chunk in your pocket) if your business grows the numbers will change dramatically and the deal may not make sense through those lenses.  

Generally speaking you can bank on about $5,000 minimum for a single wide.
