@Kevin DuongShort-Stay Rentals (STR) can bring in a lot of cash but also come with high costs for when guests come and go and tough rules.

I am looking to use the real estate properties cash flow to also build my retirement within this process and I am just not sure how I will be able to build for retirement as well as build my home. 

Don't pay anything upfront except appraisal fee.

I outline up front with the PM areas I don't want them to handle.

If we find that the well and septic need replacement, are you willing to negotiate on an all-cash offer?

It would never appreciate to where it would be worthwhile and great cash flows on paper but not gonna happenI would bet this is common in many of these other urban low priced areas.

Additionally, the costs of fixed rate seconds and HELOC's could come down from the double digits or make cash out refinances more feasible to tap equity for those with low first rate mortgage loans. 

In my experience most condos or townhomes don't cash flow well.

The cash flow would then be used to repay the PML, possibly faster if the home appreciates in value.

Those rents qualify as income to afford a bigger home loan and to offset the mortgage payment.Its also a great way to move out and have a multi-unit property bringing in more cash per month with more doors.
