Also factor in your increased maintenance costs to get your break even. 

We have thought about going to a digital key pad but are not sure about batteries dying and the fact we would still need to catalog all the keys to these pads.There are so many factors I am hoping to gain helpful insight from some of you who may have already solved this issue.Thanks!

If so, one major factor I would consider is the quality of the on-base housing. 

., there is no simple formula, as you need to look at upcoming Capex items for the rest of your projected hold period, and need to factor in appreciation (or stagnation) of values.  

That puts you in the low end of that 3-5% range to essentially just break even from any external economical factors increasing your expenses.

Running a hotel and having a longterm rental are two different businesses and that's not factoring in the up front costs of furnishing.

For sure cant forget about that .i did factor it in my CDS rental calculator They say after the 1st one the next one comes easier so I guess we'll see..

Factoring in tolls and gas I’d be paying around $200/ month.

@Rita Naga...there's too many factors you're not mentioning and I agree with both @Marty Johnston and @Chris CambridgeJust back of the napkin off the numbers though running backwards - if your NOI is ~$86,000 and rents are $595 now, then just guestimating at a 45% expense level, this is ~20-22 units??

It's important to factor into how long it could take to get contractors when buying in the area, especially as we get towards the colder months.
