Occasionally occupied HUD homes are sold within a year if circumstances change such as a job location change or even a lost job.  

If it is in a park, there is no land value.Park rents are pretty high and I occasionally see or talk to people who are trying to give old mobile homes away and not finding any takers.The cheapest new double wide I've ever seen was $38,000, and it was double wide, but short, so not much square footage.Set up costs can be as much as $30,000 if you have to bring in utilities and install a septic.

As a new investor who is corrently renting an apartment in an apartment complex, I can see the occasionally need for a month to month lease with tenants that are disruptive and a nusense to other tenants.  

I am talking about constant late fees, the occasional is not a problem.

This isn't like a flip where you have a scope of work defined well in advance and have the opportunity to line up people to do the work well in advance especially for most landlords who only do a very occasional turnover. 

House-hacks and STR's are more unique than the occasional LTR counterpart.Furthermore, you live in Philadelphia. 

Occasionally, I'll get a serious inquiry that will lead to a booking but generally, inquiries are either attempting to negotiate a lower rate or are scams.Unless your listing is dirt cheap, 30+ day bookings via a platform that requires full payment prior to check-in, are just not likely to be scams.  

This lot occasionally floods and is in a flood zone so don’t want to build on it.

I've been told that NPN investors occasionally need to contact the property owners, and when they can't reach them by phone someone needs to go to the house to talk to them.Who qualifies as a door knocker for that purpose?

I occasionally run into a person doing flips in Sherman at the monthly general meeting of the North Texas Association of Real Estate Investors (www.ntarei.com).
