I am in a similar situation (although I've changed my goals slightly and I make significantly less than you do).Your strategy is likely going to evolve as you grow into it, so the first step is about getting your feet wet.You aren't investing as much as you are building a business. 

So don't get frustrated if they don't return your call or aren't in the office.

You probably aren't getting many people to even view it on the MLS, if buyers haven't checked to box to include manufactured homes in the search. 

Problem is only "RE pros" get to do it.There are 3 income classifications in the US - Active, Portfolio, and PassiveActive income is income derived from your job, or normal trade or business.Portfolio income is derived from bank instruments - stocks, bonds, etc.Passive income is income earned from investments.Active losses can wipe out both passive and portfolio income, but it doesn't work the other way around.Portfolio (capital) losses are limited to $3,000 annually.Passive losses can only be offset by passive gains.Real estate rental income by its nature is deemed passive per IRC Sec 469One way to get around it is to become a pro - spend more than 750 hours or 1/2 your time in real estate.But most folks aren't real estate pros.

@Kyle MasonYes, laudramats aren't "sexy." but I do hear they are profitable. 

Quote from @Nick Belsky: I usually refer clients to SpringEQ.HELOCs aren't cheap, even less so for investments.https://mortgage.springeq.com/Cheers! 

Investors who aren’t experienced, knowledgeable nor sophisticated are taken by suprise that their “promised” return hasn’t materialized.  

@Jeffrey Hayes they aren't a local company but I've used "the rta cabinet store" for my cabinets.

As I said, math and numbers aren't my strength, but I'm a dedicated student when I put my mind to something, and I know how to read and use a calculator :)Thanks for reading!

The potential risks like unpaid bills and damaged property aren't worth the hassle.
