When it comes to buying SFR at a discount in a red hot sellers market, what are some lead generation tactics most investors just aren't willing to do - either it's a ton of work or expensive.

Example:So I have a home that will generate $102/month in cash flow and that gets me an ROI of 15%.  

Many won't even talk to you, if you can't provide proof of having done at least one flip.Many property managers would take care of the property including keeping it rented as well as dealing with evictions for 10% of rents generated, not potential rent, but the actual rent being generated each month.

Only when having a new tax Id number issued for an irrevocable trust is a new tax number generated and the act of applying for one is registering.If a person living in IL owns property in WI under their own social security number and as an LLC why would they register?

Would this be a right way to evaluate whether the property will infact generate some +ve cash flow ?

As a investor you must recognise a rental property has two separate income generating streams.

I'm starting to generate leads, most of which are not the type of sellers I'm looking for.

So you can see that the more equity you have in a property generating it's own income stream the less cash flow the actual property produces.

Do you think i should sell and buy another house with better cash on cash return or just pay the principle and interest and make use of the cash flow generated?

There are many ways to generate leads, one of my favorites is targeting a specific area i do this buy targeting specific zip codes.
