We have a 3% rate so dont want to refi but the property has appreciated quite a bit so would like to tap into that equity to fund our next deal.I am having some trouble finding lenders that offer helocs on investment properties.Does anyone know of any banks and/or lenders that do helocs on investments?

If rates come down (most likely not in 2025) you can refinance or just shovel cash-flow and pay it down quicker. 

They are short term loans, usually 6-12 months, high rate, interest only payments. 

This for us is preferred over seller financed deals as we can do 65% LTV, 800 credit with someone who has net work 2x+ loan and get double digit rates. 3.

@Asim G. if owners weren't so short-sightedly cheap, PMC's wouldn't be doing this!

Or at least what are investors looking for today as far as return and cap rates?

Where to get the most recent and accurate data for things like:Unemployment dataPopulation growthJob diversity and top employers in the areaVacancy rates (eg huduser.org)Property taxes and jnsurance costsI saw bp pro and reventure and a bunch of other websites provide some of this data, but i wonder how accurate and recent it is.

The interest rate is not special nor is the 20% down (80% LTV).
