Could this potentially throw off my estimated revenue, occupancy, and daily rate numbers to skew them higher than they should be?

I've been surprised at properties that have passed conventional financing though...and even FHA....also, one could present 2 offers to seller--one for a cash offer and one for seller financing (at a higher price of course). 

It may be a little scary but if you go higher on your purchase price, 400k and up. 

We can go higher if the numbers make sense. 

A scenario where you intented to hold but something came up like an unsolicited offer, higher expenses forcing a sale, change in demographics etc.   

Hi Tom,Those revenue numbers are wild... they're higher than I would have thought but those three properties are pretty sexy. 

In your case since your properties are paid off, I don' see any reason why you would use a higher interest HELOC instead of just doing a cash out refinance.  

I gained equity in the property, and I got higher rents which lowered my living expenses while living there.

That has informed us for this year's trip, and we'll be staying in Langosta/Tamarindo, Potrero/Flamingo, and Hermosa (Guanacaste not Jaco).Of course, there are tons of beautiful places in CR, and the better climate (read: less hot) is found at higher elevations. 

If you are not building in sufficient capex, then these costs could be higher, if not much higher.
