We have one other mobile home park and this property will determine my desire to buy more or sell.

Does anyone have much success buying SFH with seller financing? 

Don't buy beyond your means when it comes to construction.

I've also had guests buy their own TP and trash bags and leave the extra.As for toiletries, I leave the traditional "Starter Set" of shampoo, a little bar soap, conditioner, and lotion  (the tiny hotel bottles). 

An example of one package we have is a Romantic Package - $199. 12 Balloons (buy the helium tanks and keep balloons on site for your team or use a local shop)Rose Petal Entry Way (bought off Amazon)2 Dozen Roses (local grocery store for $10-15 each dozen)Led Candle Display (bought off amazon and reusable)I Heart U Signs (amazon and reusable)Champagne (or wine if they want)This equals around $60-70 each time and we pay our cleaner $40 to set up.

Based on a quick answer from Perplexity it seems like there would be no issue with you buying the home and collecting passive income, but you may not be allowed to manage it yourself since that is considered active work.

If you buy upscale (desirable) properties in desirable areas as opposed to affordable (undesirable) crapboxes in undesirable areas you won’t need to entice tenants.

I just finished reading The ABCs of Real Estate Investing and ABCs of Buying Rental Property by Ken McElroy.

Based on your numbers, and assuming you have a credit score high enough and have never filed for BK, you shouldn't have an issue getting approved for an HML to buy/rehab the property that I would estimate at about $370k-$375k (which includes 100% of the rehab costs).

I'd buy one, they'd buy the next.
