If it's not condemned already then it shouldn't be as difficult to get work done to it.

Yes, I understand that property management is difficult and tenants can be pain but failure seems (a total loss of time and money) seems impossible to me.As an Owner occupant If I don’t have tenants then I could drop rent and although rent wouldn’t cover the mortgage it could at the minimum subsidize my living.

In Florida for example Parks with > 50% Tenant Owned Homes can veto an increase deemed unfair to them (e.g. it was raised to much too fast).  

If this is a SFH with in law, the tenant has the right to move back into the unit at the prior rent except for any normal increases after capital improvements and rehabilitation of the units have been completed. 

After some investigation I found that there is very real to get a possitive cash flow, different that in Israel, that I think its quite difficult.

But once again if the park/development is not in the path of progress and/or in a blighted and/or run down and neglected area you may have a more difficult time.

It can be difficult to get your buyers in to see the property and usually landlords that are motivated tend to have problem tenants. 

However, you can still try and get a line of credit from a lender with your equity, but it may be a bit more difficult as most lenders are not going to offer lines of credit on investment properties.  

Honestly, none of those items are too difficult however if this is your first property I would probably reconsider.  

I know it isn't a significant amount by many standards, but it will allow you to increase your portfolio and leverage what you have to build equity.
