I have developed an startup RE proposal and I am looking for an experienced RE investor.

Jason,I think you’re right and that’s what I’m leaning towards, but I definitely see the others’ points too about allowing bad habits to develop.  

Don't sign a listing with any of them just ask their opinion of what you should do with the property.If you sell there are several ways to defer gains including 1031, contract sales and opportunity zones.If you don't want to sell you can always develop the property yourself or in partnership from ideas you get in the above process.

Yeah Age of dwelling can be a factor but its still under 100 years old.

Does APR ever play a factor?

I know if you're buying in a development prone to assessments, this can have exactly the opposite impact on your risk, so I would recommend doing a little research on the HOA: - who is president / serves on board? 

Factoring other "hidden" expenses like vacancy (when you don't have a tenant in there, you'll be paying the PITI and HOA!)

I'd like to transition into multi unit investing some day because in my head I see it as more manageable but with a PM in place maybe it doesn't matter.For my day job, I'm a software developer (Android historically).

Besides, they always have extra open houses you can hold to develop your clientele.After few sales you'll be an expert on the process and won't need any training.Well, it might take longer if you're doing it part time though but you'll get there.
