Floating rates have crushed some big multifamily syndications of late.

I planned to move it into LLP after a year due to Freddie Mac restrictions.I’ve done my own research and seems the rates are worse then what I’d get as a 2nd home for LLP. 

I would say your best bet for your best rates and best payments would be a residential mortgage company.

The HEI/HEA is not feasible because of the percentages most companies are wanting to take (some are over 50% of the appreciation from the date of the HEA).The biggest question is that we'd be losing our 2.875% rate, which will be paid off in 15 yrs.

If you can do one successfully I could imagine you could do two, but do you have the resources financial and time/manpower to operate two deals at once. 

Since interest rates went up, hard to find cash flowing deals so I had to learn the terms business.

Given the current environment of high prices and high interest rates, it is not likely that a taxpayer will pay tax on rental income for properties purchased now.

The information I am looking for would be the standard points an investor might want to know, including average home prices, median income, crime rates, real estate forecasts etc. 

A good friend of mine @Josh Green that is an investor/investor focused realtor is having great success in the Tampa Bay area.
