I bought the land for $250k ($100k down and $150k owner finance).

We have a 14-page management contract that we've added our real experiences to over the years, with the intent of protecting both us AND the landlord.

I find that it’s one of the cheapest ways for tenants to pay rent as other softwares charge high fees to tenants and / or the landlord.

I would do absolutely nothing.There is no reason to compete with stupidity as it will weed itself out.If one property comes to market at $400-$500 cheaper than actual market rents ONE lucky person will get that property and one foolish landlord will be losing a LOT of money.This would literally have zero impact on my ability to rent my place and I wouldn't for one second allow it to influence my pricing strategy.

I pulled up homes on Stetson Cir 95691 and a 5 bedroom 3 Bathroom 2,377 Sq Ft. home is quoted on Rentometer as $3,218/mo average with a +/-2% range on a 36 mo look back and 1 mile radius - the radius is important so as not to include Land Park homes across the river.

What ltv on the land and what on the build? 

Note however, as of October 1, 2023, Connecticut Landlords must return tenants' security deposits, with interest on the deposit, within 21 days and not 30 days.

Is there any suggestions on WIFI providers for landlords to use specifically for a security system.

I think maybe you should consider land, or mobile homes.

You bid land value.
