I'm a 33 yr old married Austinite Healthcare Software Developer by day, and an enthusiastic RE Investor by night.

With modern technology lenders and auditors are able to fully audit their loans using AI and machine learning -- rather than looking at a few percent they are able to analyze them all.

HI Eduardo, We just finished DIY software for this very purpose.

It depends on your climate, you might do an energy audit or just switch to electric, it doesn't seem too out of line for four units though $35 ish dollars per month depending on the size of the unit and how much they use the climate control.

Is this software can help to manage expenses and payout.where to get it.

Take a look at this logo making software - you can find there many good ideas which you can easily adapt to your needs.

We just purchased a 15 unit multifamily property and are looking into a good property management software and tenant portal. 

In an audit you can be found liable for use tax on those items.

Are you skip tracing using REI Skip or another software?

don't forget about mowing, snow plow/salt, some turnover, taxes for your manager/workers comp, free lot rent, money for your management time, accounting software, LLC set up cost Your going to have more of a greeter in a park like this, which would be free lot rent only and maybe $5 a lot...smaller parks have really thin margins...if you have 2 tenants move out, die, leave town, get arrested, whatever, you then lose 14% of your tenant base and monthly income for the property, get to 5 tenants and your at 40% which could throw your loan into nonperforming very quickly unless your willing to come out of pocket on something like thisjust to show your top gross revenue will never equal 40,000(210*14*12=35,280)just do your diligence and i wouldn't pay more than 200k for something like this...and thats a stretch or if there willing to carry some of the papersomething this small, don't turnover to a property management company because they don't know what their doing normally with a park like this and their going to charge 10% of revenue probably.
