In addition to those I would also suggest making a commitment to going to local meet ups and networking events in your area.

Every property i use it i make additional tweaks.  

Additionally, the Villages are close by and with an aging population it attracts a lot of healthcare field workers.Now, with a lot of rental properties you may run into slightly longer vacancy periods if you have a unit turn at the same time as others, but generally speaking renter demand is solid. 

Either way it would be a grey area, selling a house with a different amount of units/bedroom/bathroom seems extreme though. its an auction site, I have seen auction sites miss the fact there was additional lots in a sale.

Then we review the submitted file items and come back with questions or ask for additional documents it is a normal process.

@Colleen F. unfortunately, AFAIK, there is no other resource than go to small claims court and go after her, which will take me $2-3K in additional legal fees.

A less then full investigation may result in one thinking that the house and or the house and tennis court lots were what was being sold.As I later found out, a newbie tax lien investor thought they were getting a great bargain by outbidding other misinformed investors and paying the back taxes, legal fees, and an additional $34,000 (overage) which the county forwarded to me.  

In most single family zoned areas adding a single ADU is not a value add meaning it will not add more value than the hands off cost of the addition.  

In both you are now paying taxes on an additional $1K/mo.

Perhaps you could consider hard money in addition to private money?
