With regards to your 3rd question about some other areas,this is something that you have to research on your own Based on solid real estate principles I.E where there is employment and there is a demand for Rentals.

I know that all of the principles apply when talking about real estate investing in general, but just want to make some local connections if possible.

higher fixed rate 2nd, but it's small money AND paid off in only 15 yrs, then upon last payment of 2nd mtg....BAM....your payment on 2nd goes away and you're left with just your 1st mtg. which you can then start pounding down the principle on it and pay your house off early.But all that is great, but a person under 45 trying to catch up to where they need to be for retirement  would have to be a financial moron to start knocking down a low tax deductible rate on a home loan vs  investing in IRS, 401Ks, annuities and/or start paying off non-tax deductible debts. 

Found this in My Texas Real Estate Principle 2 Book"TMARR requires that all persons who conduct assessment and remediation of mold be properly trained and licensed by the state.Under the rules, a person is not required to be licensed to perform mold remediation in an area in which the mold contamination affects a total surface area of less than 25 contiguous square feet.

I understand the over-arching principles behind the BRRRR strategy, but I have some questions that i was hoping some experts could answer below.I've purchased my first property in cash.

But don't neglect that the portion that you are living in is also providing you benefits in mortgage interest write off, discounted living expense, and forced equity through principle pay down.  

After talking with the seller, I can tell that negotiating a low offer is very possible.Here's the issue: she mentioned that there is a mortgage on the house and that the principle balance is $142,800.

If she's single she'll be exempt on the first $250K of gain on her principle residence, (1/2 of the house?)

I put $10k down on a property and I make $1k on it that year thats 10% ROI. you put $10k on the principle of a property and your monthly payment on the interest goes down $80 a month would that be a 9.6% ROI?

When I opened the Dean Witter account, I had two years in a row with no vacancies.So, bottom like, it's the KISS principle, basic CASH MANAGEMENT.Now, as I explained to you earlier, my job in the company I worked for involves making accrual entries, so I know what it's all about, and what it doesn't do.
