I did get lot rate for a similar rural park that is about 40 miles away, and they charge $350 per month, which is decent. 

With the transfer tax - you're being charged 2% of the property value (not the loan amount)!

And not knowing their numbers also makes it next to impossible to know if you have a bad PM that's eating into your cash flow as well (Like Vacasa charging $800-1000 a month for elecrtic on a 4/3, 2000sqft house with a pool). 

The first few times, I didn't charge a late fee.

My top priority is having maximum flexibility with what I can invest in within my HSA, second priority is ease of use and convenience of the investing platform, third is minimizing any account, trading, or management fees charged by the HSA provider. 

When you are pricing out your offers make sure to price in how much you are charging for assignment of contract.

Also make sure to build on a property located in a desirable location with larger pop density and if holding for rentals, charge median rent for that market as lenders want to see a bigger pool of buyers/renters available to occupy/sell. 

This is because there’s a cap on how much someone is willing to pay to rent a home today.For example, even if you own a solid property worth over $600,000, the maximum rent you can charge in my area is $4,000 per month.

Most renters cannot (or will not) take proper care of a pool.So...if you decide to go for a pool property, make sure you have it maintained...and charge it to the tenant.

I would also give her x amount of days to move but let her know you will have to charge a prorated fee per day after that to move for occupying both units.
