I told them they could stay forever, but I needed to bring rent up.

The commute may be small for a big city, but it's forever for the locals here. 

Out of the 20 letters I've sent, I've had 1 guy get back to me and we were in discussions but weren't able to find a price that worked for the both of us.The issue is that I only have a few houses on my mailing list so far (just places I've walked or driven by that caught my attention), and blindly searching every street and address # to see which houses are actually legal multifamily will take forever and doesn't seem efficient.I know the data is publicly available, I just don't know how to aggregate it in a way that would be efficient and useful for blasting out marketing mailers.Are there any websites that can pull massive lists of all multifamily houses in my area?

I think this would make sense in the long run for the rental property as it will extend the life of everything it touches like the Sink, faucets, showers, water heater, dishwasher, and Clothes washer while also providing clean drinking water in addition to the reverse osmosis drinking water system I already have installed.The main problem with this hardness level is that we get a major deposit buildup on all of these items, which will eventually clog up the faucets for tenants and lead to rusty shower enclosures that take forever to clean.In addition to this, it looks like we could likely have the salt added every couple of months by the property managers in addition to that it would allow for a quick inspection from them, and then also we would instead bill the cost of the service onto the ledger for the tenants.For reference, it does not look like the landlords in the area have water softeners.Thank you everyone for your input ahead of time.

MHPs with SFHs are albatrosses unless you plan to live in the house and live there forever. 

Quote from @Kent Ford: Quote from @Jay Hinrichs: Quote from @Kent Ford: Quote from @Jay Hinrichs: the reasons you post.tax's  somewhat limited development regulations compared to other markets. work force   also close to Mexico and all the folks streaming in that need housing.building cost still lower than most of the country.Land forever .. no shortage sprawl is not a bad word.Political out look  conservative business friendly compared to West coast. 

I tell them all they can stay here forever.

And, in having to decide where to borrow funds from (others, hard money, our own equity, our own cash), we went with our own equity because it was the cheapest and most readily available capital.As a relatively new investor (i've been doing LTR's forever), I don't yet have solid relationships with others in order to move quickly with "OPM".Thank you for the advice here.

You'll be fighting an uphill battle forever if you try leasing outside of the summertime.

I have lent facts, you reply with opinions, this is just go on forever long as your locked into opinion bias.
